Counting blackjack at casinos actually has asymmetric upside as OP words it. Most of the time, you're placing minimum bets slowly losing at -0.5% EV a hand, gaining information on the count. But when the count is high, you're making 8-10x bets at 1 - 2.5% EV and raking in so much, on average, that you come out ahead at like EV 1%.
