You can literally use Chrome, Workspace, Drive, Android and Maps without seeing a single ad, without an ad blocker, without EVER using google search, for free.
Also Chrome exists primarily to ensure their ads business remains healthy i.e. they have massively watered down privacy restrictions.
Theres a reason that you have to log into a Google account to use those services, which means agreeing to their rather large TOS.
Buying something doesnt necessarily mean you have to pay money for it. Your time and information is worth something too.
I've never heard of Google doing this. Google sells access to and the attention of their audience. They do not sell personal data.
