Probability of being dealt a certain starting hand
There are a total of exactly 1,326 different starting hand combinations in Texas Hold’em poker. However, many of them are practically identical, e.g. A♥K♣ is exactly the same hand as A♦K♠ before the flop. If you group these identical hands together, you get 169 different starting hand groups – 13 pairs, 78 suited combinations, and 78 offsuit combinations.
The following table shows the probabilities and odds of getting dealt specific hole cards:

How do you calculate poker hand percentages?
To calculate preflop probabilities and poker odds in general you just have to do some combinatorics. There are ways to deal 2 hole cards. So that’s the total number of possible preflop combinations. The symbol in the middle of the formula is the socalled Binomial Coefficient. It calculates the number of ways of picking 2 cards from a deck of 52 cards if the order of the cards doesn’t matter.
Now let’s say you want to know the probability of being dealt aces preflop. We already know there are 1,326 different twocard combinations. Exactly 6 of those are pocket aces, namely A♠A♥, A♠A♦, A♠A♣, A♥A♦, A♥A♣ and A♦A♣. This means the probability of being dealt aces preflop is exactly .
For all other possible hands and ranges, you can calculate the probability in the same way. Just count the number of combinations and divide by the number of total possible preflop combinations.
The formulas in the tables above and below show how each probability is calculated.

Odds of running into better hands
It is one of the biggest fears poker players have when holding queens or kings before the flop: another player wakes up with aces and takes down the pot.
If you are playing against a single opponent those events will occur very rarely. If you’re holding kings, for example, the probability of your opponent holding aces is less than 0.5 percent.
But the more players there are left to act behind you the more likely it is that one of them has your premium pair beaten. Another example: if you’re holding jacks under the gun at a full ring table, the chances of at least one opponent behind you holding queens or better are already more than 11 percent.
The following table shows the probabilities of running into better hands when you’re holding a premium hand and how often you can expect certain scenarios to happen in the long run (e.g. on a full ring table you can expect to be dealt kings and run into aces every 5,737 hands):
