Yes, it's possible. It's also possible to win big at Craps and
roulette, &c relying on luck. We've all seen it: huge wins at Craps,
blackjack, Roulette, and Poker. There's that one fish who just
can't do any wrong. Just the other day, I pick up (A,A) and UTG puts in 2.5BB. He gets called multiple times, and so when it gets to me, I put in a big raise: 20Bigs, and get one caller. Flop comes: (8, 8, 4) and we go all-in for 100BB stacks. He shows (4,4). Did he make a good play here? There are 48 flops with a pair of fours, 2112 flops with one four, or 2160 flops out of 19600. That means a probability of: 110.2E-3 or 8.07 : 1 against hitting three fours or better. The fish called off another 17.5 Bigs. He needed to win at least 141.225 Bigs just to break even. Since the stack sizes were 100 Bigs, he made a
very -EV call. Yeah, I suppose he "thought" he was being clever, calling with fours to crack aces or kings, and he got lucky. While he was breaking his arm patting himself on the back for being SOOOOOOO clever, he
still made a bad, -EV call that will cost him
loads more than he won. His
expected value here is -11.23%. He'd be twice as better off playing Roulette, and you probably know just how bad that deal is. Bad players making these bad plays is what makes the Poker world go 'round.
Dave Sklansky explains about luck:
... Expert players do not rely on luck. They are at war with luck. They use their skills to minimize luck as much as possible. They figure they're getting the best of it and leave lucky draws to their weaker opponents. To the extent they are getting the best of it, they will win more than they lose... Beginning Poker players rely on big hands and lucky draws.
