Exact, not simulated. JJ means a pair of jacks and AQs means ace-queen 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 jacks is the only made hand right now, but both of ace-queen's cards are higher than it. Six cards in the deck — the aces and the queens — pair ace-queen up and put it in front.
That is why this is close rather than one-sided: the pair of jacks wins 53.9%, ace-queen wins 45.7%. The pair of jacks is ahead on every board that misses those six cards, which is most of them, but it is only ever one card from losing the lead.
Ace-queen 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 42.9%, so the shared suit is worth 2.8 percentage points.
The pot is split 0.4% of the time.
