Not going to lie, it's a holistically bad experience, very similar to iOS in this regard. But Android doesn't show ads. The closest thing would be the Google Photos pestering to back up to cloud, things like that. It's per app, and usually there are better apps to replace the offending ones. (And vendor garbage can even be uninstalled, although it's very deliberately inconvenient to do.)
Bonus points for having Brave browser with built-in adblock, for the free YouTube Premium-ish ad-free experience.
