I think the point is that while hard work has a strong positive correlation with success in most circumstances, the scale of that correlation is dwarfed by other factors like where you were born, how you were raised, and who you have access to. Working hard is like going uphill: anyone who does it is getting higher, but some people are busting their ass just to climb up a trash heap and others are getting to the top of Everest by helicopter.
