Was this the anonymous group?! pls help

Ok so long story short i was playing and talking to this guy on codm, bunch of random stuff but he asked if he knew what "anonymous" was, and do said no. He was basicaly telling me he wishes he was a part of it or whatever, as was talking to him i started talking to this one person on instagram im not gonna go too deep into it it but i guess it was illegal, it involved drugs and stuff but thats it, as i was talking to him some random person requested to follow me, and message me i accept it and he was telling me, "why am i doing this why am i doing that", basically telling me stuff no one should know. It had to have been 100% the person i was talking to on codm, i gave that person NO info on me, so its just really scary how he was able to see whatever im doing on my phone. Theirs no doubt it wasnt him, im so scared tho again the stuff was illegal (not gonna get into it, not too bad, just drugs) but yeah, im curious on wtf that was. There is a possibility it couldve been the person i was talking to on ig trying to black mail me but i doubt it theres no reason anybody would do that. Can they even do that? see exactly what ur doing and hack all ur stuff, JUST from your codm account?? pls lmk im lost
