You're the one missing the big picture Hustle.
You don't need to win more hands than the dealer to be up. In BJ you decide when the hands are doubled, not the dealer. Winning 43% against 48% is very good even with same size bets. The guy did not need to win the big bets and lose the small ones, and that was not what happened for sure.
For every 999 losing guys that came here screaming "rigged" there is one lucky fellow who beats the house.
But the house is not willing to lose even that one time.
