"Different kind of ads" - are you sure?
It looks people know Google (Alphabet) very little.... and still believe it's still just a search engine with some free nice apps and now a browser.
Do you know DoubleClick, probably the largest ads platform around, is wholly owned by Google/Alphabet? And DoubleClick delivers ads made by others?
Google doesn't live of the "paid search ads" on its search page only, or Youtube, it does live of ads pushed by DoubleClick on many other sites that have nothing to do with Google but using DoubleClick to get paid to show ads.
Google, through its own sites, YouTube and DoubleClick, dominates the ads market, with the only competitor, still behind, being Facebook.
Any decline in ads revenues if people start to block ads in their browsers would impact Google/Alphabet a lot....
