NONE of that data can predict a random occurrence discussion that goes in a specific direction.
A great example is something that happened to me in 2015. One night I was out with friends, and one of them had a really bad panic attack. The next day I was discussing it with a colleague during a smoke break, who recommended he gets a clip-on pulse oximeter. No searches, nothing, literally just a half minute detour in our chat. I repeat, nothing was typed in or looked up or in any way entered into any computer intentionally.
Five minutes later we're sitting in front of our respective computers and I start getting ads for the very thing. Mind you, we're still at a point where nothing noted during this discussion was entered into any computer. Explain this.
Nope, as only ~4 people remained at that point, and they wouldn't even be thinking of researching this topic.
