I mostly agree with your point but this isn’t the best analogy because while you’re allowed to learn to draw Jigglypuff, you probably could get in legal trouble for distributing or selling those drawing if it’s not fair use. I think a better analogy is using Jigglypuff drawings to learn how to draw things like that in general and then creating your own character that’s not exactly the same but uses some concepts you learnt
