History.com is NOT a reliable source. In fact, it is a horrible source. They are full of conspiracy theorist and alien believers. In this article, they don’t even have any citations, just made up shit apparently.
Agreed History.com has some wacky articles, but these numbers come from Richard Overy, a respected and well-researched historian. But feel free to do some pleasure reading on these:

Wikipedia is also not a reliable source. And most of what is sourced about Stalin is hearsay from defectors. Truthful sources about Stalin are not easily found on the west. The majority of them are altered anti-Soviet propaganda.
