The sentence doesn't read that way, but if that's what they meant, it's just as wrong.
YC's publicly-stated strategy from the very beginning has been to cast an extremely wide net, knowing that most wouldn't amount to much but the outliers would return enough to deliver a huge outcome overall.
And a key part of their strategy has been to be so founder-friendly that most of the promising startups would want to be part of their program.
If you look at the number of "unicorns" that have emerged since 2005, it's remarkable how many went through YC.
It's also notable that basically none of the spectacular boom-then-busts went through YC.
That's not "dumb luck", it's a well-thought-out strategy that has been proven to work extremely well over a decade-and-a-half.
