Exact, not simulated. KK means a pair of kings and AQ means ace-queen: 96 legal ways to deal the two hands, and every one of the 1,712,304 possible five-card boards dealt for each — 164,381,184 board-and-hand combinations in total, each one scored by the same evaluator the calculator uses. Combinations that are the same hand with the suits renamed were counted once and weighted by how many they stand for: 6 distinct suit patterns stand in for all 96, which is the same answer for 16 times less work.
Why it comes out this way
The pair of kings is ahead before the flop, and only one of ace-queen's cards — the ace — beats it on its own. Three aces and three queens are still in the deck.
Ace-queen wins 28.9% of the time: pairing the ace is the common way, while pairing the queen is not enough on its own, because the pair of kings still beats a pair of queens.
Suitedness is part of the answer: against the pair of kings, AQs wins 31.6% and AQo wins 28.0%. The AQ wins figure in the table is the average of both, weighted the way they actually come out of a deck — one suited combination for every three offsuit.
The pot is split 0.4% of the time.
