The "return to player" numbers for lottery tickets are on the order of 60% https://wizardofodds.com/are-lottery-players-smart/.

Similarly only a small percentage of people also are problem drinkers enough to drink and drive, and the small percentage of trips while impaired result in accidents. Yet the blast radius of the damage by that small percent is such that we decided long ago that serious laws and enforcement is a good idea.

Just because only a small percentage of people
