Final hand is rare, but not so improbable
It always bothers me when 'experts' say how the odds of that final hand are so improbable that it makes a joke of the movie.
Really? Watch the following video and then let's talk about improbable!

The odds of the Cincinnati Kid hand are about 45M to 1. The odds of a Royal Flush vs Quad Aces is 2.7 BILLION to 1!!! And, yet, it happens!
Any hand that can happen WILL happen, eventually. If I worked out the odds on some of the bad beats I've been involved with, I'm sure a couple of them would rank up there near the Cincinnati Kid hand.
