At least one of us was dealt King-Small eight times in a row given only 4 cards total at a time.
That's information I didn't get. I assumed (making an ASS of U and Me) that you were the one getting the sign from God, therefore you were the one getting the miracle hand. This new fact makes it extremely even less remarkable. Such math is extremely tricky. That's why people lose a bunch of money at cards even when they get good hands and assume the odds of such a hand are more remarkable than they are.
Ignore the flop and the river, just focus on the four cards dealt to the two players.
If it were just me calculating my own hand, the odds of getting a "King-Small" would be
(4/52) times (32/51) That's 4 out of 52 cards that could be the King and then 32 out of the remaining 51 that could be "small."
That comes out to (4 times 32) / (52 times 51), or 128/2652 which is 0.04826 or 4.8%.
Since we don't care whether it is the first or second card that is the King, we can add
(32/52) times (4/51) which is essentially doubling to 9.6%.
But we have to go further because we don't even care which of two hands has the "King-Small." I won't tabulate the slightly increased odds of this difference (after each card, there is one less card remaining so it goes to 4/51, then 4/50, then...) I will just accept the slightly lower odds and double the above calculation. Afterall, in Poker, you don't know what the other player has, so you calculate your hand separately. But in the end, if only one of the hands has to be the miracle hand, then the odds are twice as likely. It doesn't matter one bit what the other player has, even another "King-Small" when tabulating this.
So the odds are closer to 19.2% that someone will get a "King-Small" hand. That's less than (but close to) one-in-five.
The odds reset for each hand. A streak of hands played, sooner-or-later, a long streak such as this is not that remarkable at all.
