Generally an animator isn’t going to do much drawing themselves. I’m a web developer, I do not design websites. I just write the code that makes them work. In a complex undertaking like a website or an animated television show or game or something, the art is handled separately from the tech, because generally you need a different mindset and different skills to do each well.
I’d say that having done a lot of drawing in the past is going to make you a better animator, but it’s by no means necessary to be good at it.
