Why can players easvesdrop

other players heard me through my tv I am guessing, during a ranked tournament they can hear what I am saying when I don’t have the chat button on, and I am in not in a party, I can tell that players were playing atogether helping each other all trying ato get me out. I am usually not at the level. I could tell by emotes, clappping to early, praying to get me out, and someone messaged me, accusing me of cheating for naming their hands. I always guess what someone has based on what I have. They ususlly have one card up or down or the same. I heard her through my tv, and i said I think she can heard me., and she’s cheating. She messaged me and said yes, I can hear you, and your are cheating why do you keep naming my cards
