You’re NTA. You’re 13 years old. You shouldn’t have to “prove” that you can draw anything amazingly on the spot. Literally no one is going to expect that of you. Your mom should see that it’s just simply a passion of yours that you’d like to pursue further so you can improve, not that you’re just trying to impress people with it. She seems to have her own insecurity issues that she’s projecting onto you. While you also shouldn’t expect to just get an iPad out of the blue just because you want one, she should see how much this means to you and make it a birthday present. You do not have to prove your worth to anyone, including your mother.
