How do they earn money?

Hi friends.

I've been looking for content so I can make videos on tik tok and shorts, and there is always this questions I have: how do they make money and how can I follow their steps?

I will give you some names of spanish (I speak spanish) creators so you can have an idea:

Holayeyo

CuriosoDan

Biologiadesdecero

The common thing I see in all of them is that they do not have sponsors or adds (at least not explicitly), and they have high quality edition (at least that is what I think, so that is probably their main job.)

I am aiming to make that kind of video: Short, dinamic, with effects so people can keep watching.
