When you try to X out a Google ad and click "Stop seeing this ad", you get a choice of replies:

* Ad was inappropriate
* Seen this ad multiple times
* Not interested in this ad
* Ad covered content

The result of any of the choices is you see that ad on every single site you visit that supports (or is supported by) Google ads.

Your other initial choice besides "Stop seeing this ad" is "Why this ad?", which then directs you to disable the Google ads from being able to collect info based on your browser history, after which you will see that ad on every single site you visit that supports (or is supported by) Google ads.
