It's impossible to perfectly distinguish them. Anyone that seemed to be skillful could just be incredibly lucky.
But you can get determine a likelihood that they are lucky by monitoring their performance over a long time / lot of games. It's just that if you are evaluating a whole lot of people looking for a rare skillful person, you need a whole lot more time/games to be sure they aren't lucky than if you just had one person to evaluate.
