Adding to that fact, I'm in the process of applying to an animation school so I had to do (and still doing) a ton of life drawings to prove basic artistic competency. Granted that's just in the fundamentals mind you, you don't need to be Michelangelo, but you do need to know how to draw people, environments and animals on some basic level. The first ticket to get into the school is proving highschool completion or other acceptable record of academic ability, the second submission, your portfolio, actually determines if you get in or not.
That being said, that's the schooling side of it. I have heard it's possible to get into jobs sans school but you're going to be competing against people who were put on a hamster wheel to grind out their studies over several years, so it's no simple feat. Including with that, they probably come with industry ready tool knowledge and potentially connections/ internships.
From my research that seems to be entirely the same for the professional world. Granted, "animation" is a bit more varied and from the little I've read, 3D animation seems to rely a lot less on drawing ability? Maybe someone who knows more about it can confirm or not. I've read in passing that 3D artists will describe having no ability at all to draw, they can only seem to understand art in their chosen medium. (And vice versa.) At the end of the day none of this is to 'gatekeep', it's a very plausible field and if you wanted to take the schooling route, all you have to do is meet bare minimum standards. The course will take you the rest of the way (+ your own dedication, of course.)
