By calculation there are 133,784,560 possible 7-card poker hands.
The odds are 1::17 that you will catch any pair as your hole cards and, by inference, the chances those cards will be aces is 1::221.
On the other hand, mathematics, calculations and odds will least affect play in Texas Hold-Em than almost any other poker game. HE is a psychological game more than anything else. With only two cards hidden in each hand calculation of the odds of catching a particular card is relatively easy whereas in, say, 7-Card Stud, there are more cards isible and the calculations can become more difficult, what with having to remember who folded, how many cards they had exposed, what those cards were, etc. I'm not saying that psychology doesn't enter in Stud play, but the effect isn't as great as it is in HE.
