TikTok's recommendation algorithm is probably one of the best. It puts content first, giving what seems only a passing weight to follower count.
That doesn't mean that having a big follower count doesn't increase you chance to go viral and gain a lot of views, but it is much more likely for great content from a small creator to go viral, than mediocre content from someone with 500.000 followers.
You can also see this in that successful TikTok profiles often have a much higher view-to-follower ratio than something like YouTube.
