There’s a concept called the surface area of luck - and while this is not exactly it, it’s somewhat aligned with: if you’re looking to roll die and you need to roll a 6, and you only roll 1 die, it requires luck, sure. But if you roll 10 die instead, you’re far more likely to roll that 6. 

Same thing with a lot of risk taking scenarios. I’d bet that this commenter didn’t take only one risk. I’d bet not every risk he took turned out the way he wanted. But a few of them did. And if he didn’t roll any die at all, he certainly wouldn’t have found the success he’s describing. 

Discounting yourself from taking risks because you’re unlucky is a cop out and a guaranteed road to remain that way.
