How many people play it
Under the crowd model, 17 is picked about 1.22× as often as an indifferent choice — 15th most popular of 54. 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: 17 is drawn with probability 5/54 tonight whatever it did last week.
