if you wanted to ask if youtube works with tor or not, then i guess you can try and see it yourself, but i'm pretty sure that most - if not all - exit nodes are already blacklisted on youtube and even if you manage to find working ones, the streaming will be slow as hell
i'm not sure what's your angle, but if you're thinking about creating and accessing accs, uploading videos to youtube using tor then that's a bad idea, if you are somewhere where youtube is blocked and you want to unblock it, there are free VPNs or webproxies for that, you don't need tor
