Hillary Clinton won the popular vote by almost 3 million and still lost.
If Kamala wins the popular vote, how much does she have to win by to flip
the electoral college to her side?
Does it matter what states she wins in if the margins are low?
Depends fully on what states she wins
This
It’s all about the handful of swing states, 2/3rds of the electoral votes are basically locked it. She might get a few from out of left field but that has yet to be seen
Take Nebraska, I can tell you right now we will give Kamala 1 electoral vote and the remaining 4 to Tump.
Edit: Anicdotal evidence
This will help you a bit to answer your own question: https://www.270towin.com/ You can play with scenarios there.
how much does she have to win by to flip the electoral college to her side?
This misunderstands how our elections work. If you win a state by one vote (offer not valid in Nebraska and Maine), you get all that state’s electoral votes. If you flip several thousand votes in a few states, Trump wins the 2020 election even though Biden had around 7,000,000 more in the popular vote total. Also, if you’re from the UK, Americans are a little idiosyncratic in their voting. A good deal of people do the equivalent of voting for a Tory even if they wanted Labour in power. It’s called vote splitting, and it’s generally a terrible idea.
If you win a state by one vote (offer not valid in Nebraska and Maine), you get all that state’s electoral votes.
I’m going to pile on to your good answer.
Since you only need 51% to win all of a state’s electoral votes, any additional votes beyond 51% could be considered excess votes that are not helpful. The system rewards candidates whose supporters are spread around, and punishes candidates whose supporters are heavily concentrated in a handful of states.
For example, in 2016 Hilary Clinton got 4,269,978 more votes in California than Trump. That’s 4,269,977 more than she needed to win the state. Meanwhile, she lost Michigan by 10,704 votes, lost Pennsylvania by 44,292 votes, lost Florida by 112,912, etc. Hell, she lost Texas by less than a million votes. If Hilary’s supporters in California had been spread around in other states she would have won the national election easily.

This is part of why I haven’t left Ohio, have beat back on the argument that “I should just move [to somewhere that’s more politically aligned with my beliefs]” (which I’ve heard that line enough, I fully believe it’s a GOP driven talking point), and I’ve encouraged other left-leaning folks to stay or come back.
I believe this is the last election where Maine will have split electoral votes, since they joined the National Popular Vote Interstate Compact earlier this year.
National Popular Vote Interstate Compact
That doesn’t do anything until it has enough states that it actually guarantees the person that wins the popular vote, wins.
Here’s the list of states and electoral college votes:

Just don’t think about the popular vote. It has no bearing on who wins the Presidency in the US.
You can argue that it should but just accept that under the current rules it does not.
As far as your question “If Kamala wins the popular vote, how much does she have to win by to flip the electoral college to her side?” the only answer is “it depends”
It depends because as amazingly stupid as this sounds, one vote for a candidate counts either more or less depending on which state it came from.
Example of California (most people) and Wyoming (least people)
California:
Electoral Votes: 55
Population: 39,500,000
Weight: 0.00000139
Wyoming:
Electoral Votes: 3
Population: 580,000
Weight: 0.00000517
A vote in Wyoming (0.00000517) affects the outcome of the electoral college much more than a vote in California (0.00000139).
Another way of looking at it is that one electoral college vote in California represents the will of a little over 718,000 residents, while in Wyoming it represents the will of a little over 193,000 people.
Things get even trickier when you factor in the fact that some states split the EC votes based on popular vote or district, and other states are a winner-take-all (whichever candidate takes the state takes all the EC votes.)
It’s a giant complex mess and it cannot be easily related to the popular vote.
It doesn’t work that way.
There isn’t a single popular vote. There are 538 votes to be cast, votes distributed to the states based on the most recent census.
Each state then runs an election to determine how their vote is cast. More technically, you’re voting for a specific elector, but given faithless elector laws, it’s defacto a specific candidate.
Most states are all-or-nothing, whoever wins that state gets that state’s full vote count.
To win, it takes 270 electoral votes.
This is why battleground states are so important. Hillary may have gotten more votes nationally, but none of the elections were in fact national. She ignored key battleground states and arrogantly expected to just win them.
Hillary was, and remains, an arrogant fool. Not, it must be said, in the same way Trump is.
Stop worrying yourself with the popular vote. You gotta get them purple states to WIN.
