Preposterous Poker Probabilities
If you really want to understand the game of poker, you need to understand the odds! Odds are the chances of you holding a winning hand. And while odds aren’t everything, knowing the numbers can certainly help you to hone your skills and to understand some of those seemingly crazy hands.
While it’s important to hold out for the right hand to play, in Texas Hold’em, your chances of getting a top starting hand are only 2.1%! This includes AA, AK suited, and picture pairs. To be exact, your chance of getting those coveted pocket rockets is 221 to one. It’s always great to get those hands, but you can’t wait forever! Something to be wary of, though, is playing just any suited cards. You might think that it raises your chances of winning greatly, but it’s really only by around 2.5%.

Even more than that, the chances of getting a SPECIFIC royal flush are 2,598,960 to 1. You’re FIVE TIMES more likely to get struck by lightning!

As mathematician Yannay Khaikin explains, “Any time you pick up a well shuffled deck, you are almost certainly holding an arrangement of cards that has never before existed and might not exist again.” There are more ways to arrange a single deck of playing cards than there are atoms on Earth.
The next time you score AA or that coveted royal flush, remember just how lucky you are! And take a moment to appreciate your next well-shuffled deck. You’ll probably never see that specific arrangement of cards again in your lifetime.
