bro, i have drawing with my finger till now cause my cheap tablet broke, but i gotta say, drawing with your finger is better than using a pencil or a mouse, use your tablet or phone in the "horizontal" way and download a simple program like ibis paint, give it some years and you will start drawing like a god, im tellin ya, also, i think drawing with your fingers gives you a little bit of experience on the mouse, or at least thats what happened to me, but now coming back to the topic, drawing with a finger aint toture like some of yall say, its torture when you draw on the wrong way, drawing with your tablet or phone in the "vertical" way is pain, yall just gotta make your horizontal way throught that stuff and draw
