What the numbers mean
A hand's share of the pot is what it wins on average over every board that can still come: a win counts as the whole pot and a split as its part of it. Players call it equity. The ace and king of spades take 54.4% of the pot against two queens on a flop of J♠ 7♠ 2♥, the hand on the page when it opens: any spade makes them a flush, and any ace or king a higher pair.
With the flop or the turn on the table there are only a few hundred boards still to come, so the calculator counts every one of them and the figures are exact. Before the flop there can be more than a million, so it deals random boards instead, 30,000 for Hold'em and 12,000 for Omaha, which lands within about a point of the exact figure. Counted over every board, aces take 81.3% of the pot against kings of the other two suits before the flop: they win 81.1% of the time and split 0.4%.
The share tells you whether a call pays. A call of $10 into a pot that will hold $40 needs 25% of the pot to break even, and the pot odds calculator does that sum for you. In Omaha each hand plays exactly two of its own cards with three from the board, and the shares run closer than in Hold'em: the Omaha rules have a table of how strong the winning hand gets.

Questions
What are the odds of aces against kings?
Counted over every board, aces take 81.3% of the pot against kings of the other two suits before the flop: they win 81.1% of the time and split 0.4%. The kings take the other 18.7%.
How does the poker odds calculator work out the chance?
It counts boards. With three or four cards on the board it goes through every turn and river still to come, so the figures are exact. Before the flop it deals random boards, 30,000 for Hold'em and 12,000 for Omaha, and the result is an estimate within about a point.
Does the odds calculator work for Omaha?
Yes, for Omaha with four, five and six cards, with the rule that each hand plays exactly two of its own cards and three from the board.
What is equity in poker?
Your share of the pot on average over every way the rest of the hand can come. A hand with 40% equity in a $100 pot is worth $40 of it when the hand goes to a showdown.
