But the dice gets rolled for everyone and clearly success isn’t randomly distributed.

So what does that tell you?

It must be luck plus something else.

That is why I said “significant role”, not “the only requirement”, yes.

In science we have the idea of background noise - a random signal that is always there is random fashion.

And what is typically done is you ignore it. It’s always there, it’s random, and it applies to all samples.

Same with luck and success. You can control luck, so you focus on what’s left.
