Exact, not simulated. AQ means ace-queen and KJ means king-jack: 256 legal ways to deal the two hands, and every one of the 1,712,304 possible five-card boards dealt for each — 438,349,824 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: 15 distinct suit patterns stand in for all 256, which is the same answer for 17 times less work.
Why it comes out this way
Neither hand has made anything yet, so this is decided by which cards pair up first. Ace-queen holds the highest card of the four, the ace; king-jack holds the king and the jack, and its king beats every card ace-queen holds except the ace.
Ace-queen wins 62.2% and king-jack wins 37.3%, and the pot is split 0.5% of the time.
