I think you miss the point. I believe the point is if you don't try then luck won't help you. Or in other words you can't win the lottery if you don't buy a ticket.
Those born wealthy can often buy so many tickets it's virtually guaranteed they'll stumble into something that works, at least once.
No one is saying people don't have to at least lift a finger to try. Just that birth luck affords so many other opportunities that the advice of outliers and the born comfortable isn't transferable.
