It's possible. I only ever halfway learnt how to play them but still did a bunch of matches online and had fun, with usually around a 45-50% winrate. It wasn't all random flailing (although a lot of it was), I was landing reads and juggles, mixing up, frame trapping, baiting reversals and so on.
You just have to be willing to get BTFO sometimes, and maybe it doesn't work as well in games with lower playercounts.
I do think tutorials could be better... if you look at the SF6 guides they basically just require you to sit still and read without properly being able to try any of the techniques outside of just doing them once, and they try to explain a lot of nuance. I guess I can see why, but I feel like they might be better off just giving players basic strategies they can use to scam retards online to get started with. There should be more than just combo trials, too; mixup/pressure trials, defence trials and all that stuff.
