I don't think Google uses data from Chrome this way. I don't think Google actually wants to associate data with people so aggressively. It's obvious when that happens and it feels gross (this is why I stopped using Facebook 10+ years ago, I've never had an equivalent gross-out moment with Google).

I'm guessing the reason google doesn't use third party cookies is because they get higher quality data from people being signed in to Google services, and that is independent of whether they are using Chrome or not.

Yea correct. They have numerous other ways of identifying you or fingerprinting you that cookies aren't all that important anymore.
