It is not unreasonable to establish a connection between these two things. In particular, the argument that the two words come from the same family of names is quite convincing. I was also someone who only played football games on PS. I played PES from PS 1 onwards (at that time, it was called Winning Eleven). Both activities are common ground for those seeking excitement. Those who are not sufficiently satisfied while playing games may turn to betting. This does not seem like a ridiculous analysis to me. However, based on my own life experiences, I cannot say that this is a correct or generalizable conclusion...
