It 100% depends on what you like. I've been using tiktok forever and a day and all I see is funny stuff that is relevant to me. Very obscure niche things that have 1000 hearts - it's scary good at recommending relevant content.

If you are seeing political content, it's just because you told the algorithm that you enjoy interacting with that type of content.

That's why I said "perceived". Eventually something will happen and Important People will pay attention. It just has not happened yet.
