"Tracking" is a bit different, if I go to a big news site, that happens to also serve FB ads - than going to FB directly and complain that they track what I do

"Tracking" is a bit different, if I go to a big news site, that happens to also serve FB ads - than going to FB directly and complain that they track what I do at their place. And like I said, if I use a adblocker preventing to load FBs add in the first place, then how can they meaningfully track me in any way?
