So it's far more likely these comments are over-indexing on the "its all luck/unfairness" explanation than the "it's all rational" explanation given there's 100X more people who will have their egos protected by the former positioning (the ratio of executives to worker bees is like 1:100).
It’s more that the “i work hard and hustle everyday” narrative from successful people is to protect their little egos from the realisation that 90% of their success is pure luck / chance / chaos.
