> If your data isn't being sold, then no, they're not selling user data.

That’s just phrasing to attempt to weasel out of the fact that it’s selling the ability to derive the user data. It’s effectively the same thing with a layer of indirection.

Auction system is irrelevant. Unless Google is ignoring your target demographic and keywords entirely, they are selling you a stream of traffic that matches that demographic on average.
