Exactly, you see thousands of irrelevant ads every day and think nothing of it, then when 1 time an ad gets lucky, you will use it as proof "they are listening" forever after.

I had the same thing happen with billboards. I learned about some new thing I have never heard about before, and wouldn't you know it shortly after I saw a billboard selling it. The ad companies must be on top of their game, they are nor only listening to everything I say, they can print and install a whole billboard on the side of a building within minutes just before I go here.
