I think TikTok's creator fund has led to quite a large number of influencers across many interests and categories. Perhaps seeing the success that Vine failed to largely capitalize on.

Over 1 billion dollars in the US over the next three years.
One common complaint from creators I watch on YouTube seems to be that the fund isn’t high enough for them to do TikTok full-time.
So currently the flow is:
Build an audience on TikTok, have that audience follow you to YouTube where ad revenue reigns supreme.
One day that flow will just be to build an audience on TikTok.
