The average wait counts spins until the first run of 200 losses is completed. It is an average over many players, and any individual can see it on their first 200 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 200 losses has a probability of 87.14% to the power of 200, which is 1.11 × 10-10%. It is rare for any one run of 200 spins, but it does not stay rare if you keep going: across 1,000 spins the chance that it appears at least once is 1.16 × 10-8%.
The next spin is not owed a win. After 199 losses the chance of a win on the next spin is still exactly 12.86%. 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 2200 − 1 times your first stake to survive 200 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.
