Exact, not simulated. AA means a pair of aces and JTs means jack-ten suited: 24 legal ways to deal the two hands, and every one of the 1,712,304 possible five-card boards dealt for each — 41,095,296 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: 2 distinct suit patterns stand in for all 24, which is the same answer for 12 times less work.
Why it comes out this way
The pair of aces is ahead and both of jack-ten's cards are lower than the pair, so pairing up is usually not enough — a jack or a ten on the board still leaves jack-ten behind the pair of aces.
Jack-ten still wins 21.0% of the time, and almost all of it comes from straights, flushes and two pair rather than from pairing one card. Its two ranks sit next to each other, which gives them four different straights to aim at.
Jack-ten being suited matters here: two cards of the same suit make a flush far more often than two of different suits, and a flush beats any pair. The same two ranks offsuit win only 17.1%, so the shared suit is worth 3.9 percentage points.
The pot is split 0.4% of the time.
