Each ticket is another chance to win.
887 tickets were sold. If you bought 88 tickets then you have a 1 in 10 chance.
But then, as soon as winner #1 is picked, all their tickets are removed and #2 is then chosen. So then your chances increase.
By the time the first 3 winners are drawn, probably quite a few tickets are removed from the pool since statistically, the ones who bought the most tickets will tend to be drawn first.
It's all random and we're had winners who only bought 1 ticket but that is very rare.
