People are conflating "skill-based game" with "game it is possible to win at in the long run." Blackjack absolutely IS a skill-based game, although impossible to win in the long run (yeah, okay, assume the deck is reshuffled every hand).

Me pitching a curveball to Derek Jeter is a skill based game too, but I absolutely will not win it in the long run.

So, the blackjack example does not defeat Sklansky's theorem here, because skill is a factor in blackjack - skill ultimately decides how quickly you will lose. If Jeter homers off of me 70 times out of 100, that doesn't mean it was out of my control.
