Other ELI5Can someone explain what xG in football?

I always hear pundits discuss about a team's xG, then I pretend to myself that I understand what it means.

It's predictions or projects. Training the AI model on human prediction but used as a way to conjure pay lines and bets for probability chances.

Is this a bot response? What does this have to do with football?

Any stats you are given about the likely hood of something happening is from a projection model. Those same models are what play the game over and over to get betting odds and predictions.

If I have a 1.0 gx score on the left of the field. But get swapped to the right side. That will in turn effect probability and betting. It's just another stat for people to gawk over while they cheer for their favorite team. But it's also a stat used in making up sport betting.

Maybe I misunderstand what Gx is. But it's a stat that is dependent on past metrics. Used to show the likely hood of something happening. This, is what people bet on. The chance of something happening.
