Yes and no. They’re both hydrocarbons.
Coal is organic matter from dry land, so typically plants.
Oil is from organic matter that fell to the ocean floor, so microbial life, algae and the like.
But both are from and end up as the same types of organic molecules. Carbon and hydrogen.
Wow ok that’s cool… so then every* oil well is in a place that historically was underwater?

Yes, specifically shallow seas that are so rich that they go anoxic. Without oxygen, the organisms don’t break down and just accumulate.
