Kinda sorta.
The thing is complexity (an entire anatomically-correct girl in a natural gesture)is harder to learn when tackled head-on from a beginner tier. You'll improve for sure, but it'll be a hell of a lot slower; It's like trying to bench 100 pounds when your too weak to do half a girly pushup once.
The best thing you can do is start building a solid foundation out of the bare basics: starting from line, to 3d form, to basic rendering/lighting, to anatomy, and finally, style. I sum it up pretty simply but the simplest basics can take a very long time, be very tedious, and require a good deal of patience to "master". Drawing something as simple as a straight line, a clean curve, or perfect circle can take forever to do right even once, and even longer to do right every time without even thinking. It can seem arbitrary, but it's fundamental to being able to draw a sphere, and drawing a sphere is fundamental to construction, construction is fundamental to drawing people convincingly, and drawing people is fundamental to drawing them stylized without looking weird.
make sure you aren't just practicing a random array of things; I mean you can practice anything you want, but always have a main focus for your efforts. Just start from the bottom (line) and you'll improve more than if you had just doodled random stuff. Trust me, you won't do yourself favors wandering around blindly in art: look up references when you need them, always make sure you're always on your A game, and even when you feel like you've done something right, try to see what could've possibly been improved.
but most of all: have fun. Be interested. Seek enjoyment in the creation process. Most of us "git gud" types of artists are so masochistic in our desperate race for the professional standard that we can lose ourselves in the training and forget why we ever wanted to do this shit in the first place. That's not a place you want to be because it can lead to boredom, stagnation, loss of drive, and therefore slower improvement. Make sure you're enjoying the things you make (not necessarily from a quality standpoint, but actually just enjoying the process of making something).
P.S. Literally drawing everyday, having a decent sleep schedule, and shaving the fat off you're free time (gaming, browsing, t.v., movies, crazy amounts of time spent with a friend/friends, weed smoking, alcoholism) help a tonne, too.
