9 looks unusual on its own — and unremarkable among 90 numbers
Drawn 65 times in 1,425 draws against 95.0 expected, −3.19σ. Testing all 90 numbers at once means about 0.9 should look this way by luck alone, so the threshold tightens to 1.1e-4 and this does not pass it. It has also come out as the bonus ball 11 times, counted separately.
9
Number 9, draw by draw

a completed wait — darker is longer the wait still running — a lower bound, not a finished gap
Where it lands in a sorted draw
Sort a draw and 9 has a favourite seat — chance gives a small number the low positions more often. That is the shape of sorting, not of the machine.
It has shared a draw with every one of the other 89 numbers; chance expected about 2 still unmet by now. Every pair →
How many people play it
Under the crowd model, 9 is picked about 1.48× as often as an indifferent choice — 2nd most popular of 90. That changes nothing about whether it comes up, and everything about how many ways a jackpot on it would be shared.
Nothing here predicts the next draw. A number’s history is a record of a fair machine’s past, and the machine keeps none of it: 9 is drawn with probability 6/90 tonight whatever it did last week.
