It is quite obvious that it doesn't work, not even close. Anyone using some big tech software can see it with his own eyes - ADs are atrociously tailored to the viewer. Facebook shows me total bullcrap for as long as I'm using it. And using it regularly I can see how AD cycles come and go, sponsored posts unified by some theme change every several months - it can be an avalanche of t-shirts, then creepto, then some political party, then creepto again, then meme groups, then some China sponsored posts masquerading as personal blogs, etc. etc. All of them are a complete miss, then can see that there are clickthroughs, no related searches, no views. Same with Google, MS, anyone. Trillion dollar corps specializing at harvesting and selling personal data can't figure it out. Personalized ADs are a myth.
