Twitch - not different from YouTube since they display ads and they have a premium service. On top of that I can add that without female streamers dressing sexy and not always playing video games Twitch would not have as high revenue.

Tiktok. - still shows ads so they are not financing things in a different way.

Vimeo - yes, they finance their services in a different way. But it still doesn't answer how their content creators make money since Vimeo charge the content creators and doesn't allow ads. But seriously, Vimeo isn't a competitor to YouTube. I have a hard time imagining how they would grow to even a third of the size of YouTube.
