You need to block Google completely. Simply abstaining from Google services and/or using a browser ad blocker will do you no good — like 80%* of apps / the web include their tracking assets (among many others).
* Just a number I pulled out of my ass, don’t sue me
Maybe DNS or IP blocking, but blocking only in the browser likely won’t be helpful as apps (on basically any platform) also track users by calling assets on their domains.
