The average wait counts spins until the first run of 7 losses is completed. It is an average over many players, and any individual can see it on their first 7 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 7 losses has a probability of 82% to the power of 7, which is 24.93%. It is rare for any one run of 7 spins, but it does not stay rare if you keep going: across 500 spins the chance that it appears at least once is 99.9%+.
The next spin is not owed a win. After 6 losses the chance of a win on the next spin is still exactly 18%. The wheel has no memory, and a fresh provably fair roll is generated for each spin. Believing a win is overdue is the gambler's fallacy, and it is the most common reason stakes grow during a bad run.
Doubling after a loss does not fix it. Doubling the stake until a win needs 27 − 1 times your first stake to survive 7 losses in a row, and a table limit or an empty balance ends the plan well before the maths evens out. The 10% house edge applies to every stake in the plan, so betting more does not change the expected loss per unit staked.
