> bet 10 times

The point in option 1 and 3 is to illustrate that betting 10 times isn’t an option in many systems. You can’t say you should always do something because the risk reward is favorable. That’s still gambling, and sometimes a stupid decision.

The average outcome of a gamble is not the likely outcome of taking it. And even ignoring that, it’s still a gamble unless you can confidently run it at sufficient scale to hit the theoretical distribution.
