A graphics tablet is pretty much a must if you want to get into 2D digital art. I used to draw for years with a mouse, the idea now of using a mouse now is just torture lol. It ain't worth it.
Personally, 3D modelling is even more torture to me, but that is just me. But maybe you'll like it!

Maybe you should scope down. Try Animating with Photos of Drawings on Paper with a Sharpie, and arrange them into a Video with Windows Video Editor.
