In Lotto under the 6/52 + 1/25 · Oct 2012 – Jan 2015 rules — 339 draws, 6 from 1–52 (an earlier era).

7 looks unusual on its own — and unremarkable among 52 numbers
Drawn 57 times in 339 draws against 39.1 expected, +3.04σ. Testing all 52 numbers at once means about 0.5 should look this way by luck alone, so the threshold tightens to 1.9e-4 and this does not pass it.
7
Number 7, draw by draw
Drawn 57 times in 339 draws · average wait 5.8 draws · longest completed wait 28 · waiting 13 draws now
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 7 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 51 numbers; chance expects about 0.2 such strangers by now. Every pair →
How many people play it
Under the crowd model, 7 is picked about 1.54× as often as an indifferent choice — 1st most popular of 52. 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: 7 is drawn with probability 6/52 tonight whatever it did last week.
