What is the factoring of what is a chance and what is the degree of difficulty of a chance?

AFAIA, it's a data and probability generation model.

If, in X amount of attempts, somebody has shot from that position before then an xG of 1 means it has gone in every time and 0 is a statistical and legal impossibility.

So 0.9 is 9 out of 10 people who have had a crack from that position have scored

The "position" takes the below into account:

Distance to the goal
Angle to the goal
Did the player strike it with his feet or was it a header?
In what passage of play did it happen? (e.g. open play, direct free-kick, corner kick, counter-attack)
Has the player just beaten an opponent?

I've heard there's more since I checked. But I think that's around GK data, I don't actually know.
