20 looks unusual on its own — and unremarkable among 49 numbers
Drawn 42 times in 213 draws against 26.1 expected, +3.33σ. Testing all 49 numbers at once means about 0.5 should look this way by luck alone, so the threshold tightens to 2.0e-4 and this does not pass it.

Where it lands in a sorted draw
Sort a draw and 20 has a favourite seat — chance gives a small number the low positions more often. That is the shape of sorting, not of the machine.
Never drawn alongside 1 of the other 48 numbers; chance expects about 0.6 such strangers by now. Every pair →
How many people play it
Under the crowd model, 20 is picked about 1.28× as often as an indifferent choice — 13th most popular of 49. 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: 20 is drawn with probability 6/49 tonight whatever it did last week.
