ok the pot is split, lets say there are 3 people in. 2 people have 10,000 and 1 person has 9,000. the three people go all in combined pot of 29,000which equals 100%. and they all have the same winning hands. Now the two people with the 10,000 gets their 10,000 back 33.3% but the one with the 9,000 gets 30% because he didnt have the full 10,000 in the first place while the others have.

that is the per centage that both players hands will be the same. and they will share the pot.

It is the odds that both players will have the same hand in the end. If one player has a-2 and another has a-3 they will chop the pot a certain percentage of the time. like a flop like k-k-7-5-8 it would be a split pot because they have the same hand.

The percentage is the chance of someone winning the hand. This will occur if they have the same pocket pair or the same 2 cards (such as both having Ace-King)…then it comes down to who can pull a flush (assuming on the Ace-King example that they both have the same suit or if one has an Ace and the other person has the K in the same suit or vice versa, or they each have 2 different suits that don’t match the other persons suits, such as A of Hearts K of Diamonds vs. A of Spades K of Clubs), otherwise the pot usually splits between 96-98% of the time.

Like the person above said too, if someone has A2 and the other has A3, 5 cards over the 3 would chop the pot too….that will happen about 90% of the time since a 2 or a 3 could win the pot assuming a higher 2 pair on the board or a straight or flush do not show up.
