> In reality, if you have 100 5% chances of a cure for a previously incurable illness, you can celebrate each chance a lot.

These numbers are obviously entirely made up, but its worth noting that 100 5% chances of a cure, means you have at least 1 cure with (1-(.95)^100) = 99.4% probability.

If you are curing an incurable disease with 99.4% probability, celebrating a lot would be an understatement.
