I think outcome is more like opportunity + luck. Identical twins are a great example, plenty of pairs grow up in nearly exactly equivalent environments but still have radically different outcomes in life. Like a Galton Board ('Plinko')[1], seemingly identical balls (people) can start from exactly the same position, but the indiscernible differences in their makeup combined with the exponential chaos of the branching pegs (life) mean they often end up in completely different places.

That's how I see it at least :)
