Blunders, Inaccuracies and Mistakes
I dunno how chess.com ranks them. In general I think it goes blunders > mistakes > Inaccuracies.
So a blunder loses the game immediately, a mistake gives you a clearly worse position than what you could have had, and an inaccuracy is slightly less than best, and diminishes your position a little.

I would add that the scale you use for these is highly subjective. A master would call losing a pawn a blunder, while a beginner would say hanging a piece is only a mistake.
Mistake: this is an umbrella term for anything wrong, but it isn't used very often in specific contexts
blunder: a serious error that largely compromises your position, whether materially or structurally
inaccuracy: a more subtle error that may lead to a disadvantageous position if properly taken advantage of
