Am I at Risk if I Play a Game That Uses Peer to Peer Matchmaking?

I was talking to a twitch streamer about the video game For Honor, which has a Peer to Peer multiplayer system. He said he would not play it because a peer to peer system is unsecured, and any player in your game can read your IP and use it to hack your computer. Is this true, what is the risk of playing a game that uses peer to peer?
