The average wait counts spins until the first run of 100 wins is completed. It is an average over many players, and any individual can see it on their first 100 spins or never. The "at least once" figures are exact: they account for a run starting on any spin, not just the first.
What it means
A streak of 100 wins has a probability of 81.82% to the power of 100, which is 1.93 × 10-7%. Any one run of 100 spins is unlikely to do it, but over 500 spins the chance it shows up at least once is 1.42 × 10-5%.
A hot streak does not make the next spin likelier to win. After 100 wins the chance of another is still exactly 81.82%. Each spin gets its own provably fair roll, so there is no momentum to ride and no balance to correct. The belief that a winner is due to lose, or keeps winning, is the gambler's fallacy and the hot-hand fallacy: two sides of the same mistake.
A streak is a good moment to stop, not to raise the stake. The expected return is 90 per 100 staked whatever just happened, so winnings at risk on the next spin are expected to shrink on average. Deciding in advance when you will cash out is the only part of this you control.
