Please understandnim asking this question from a genuine place. I dont want the quora answer, i want the tech savvy, security expert minds of my fellow lemmings. If thats ok?
What happens to this data? What can/do they do with it? and why are so many people concerned about google tracking them?
Do i as an average user need to be concerned?
If so, What sorts of things can i do to avoid being tracked? Preferably without too much comprimise.
The addresses are here under plain DNS

Something to keep in mind is that some ISP will intercept your DNS request and redirect them their own servers. DNS is done in clear text. If you are concerned about that you can use DNS over TLS or DNS over HTTPS to hide your queries. But that is a complex set up and not all devices/apps support DoT or DoH
