Thoughts of men and women best friends?

So I recently met someone, I didn’t think it was something serious to be honest because of how this whole new scene of dating is. But he wanted the real deal and didn’t want something just physical. He communicates well, a hard worker, funny, he texts back fast etc. he recently told me he has a girl best friend who he messages everyday and games with everyday etc. I’ve had past horrible experiences with men having best friends. I just don’t really know what to think. I’m kinda overthinking everything. So I suppose my question is what are the chances of men and women being bestfriends that constantly text everyday and game with eachother.
