There is a fundamental limitation in the human ability to assess success. Humans inheritably live in different worlds therefore, their perception of key factors such as self-actualization, esteem, belonging, love, safety & physiological needs will be invariable different. I would argue that if everyone started out with the same mindset and base opportunities, with time, the environment and its scarcities would cause some to deviate towards being 'richer' and others towards being 'poorer', partially by luck, and partially by other factors within and outside each person's control. Someone that is self-made will mostly see itself's success as their personal actions and will mostly overestimate that side (E.g. I saved money while my peers were burning it on consumer goods) while others looking from outside will mostly push the (E.g. He was lucky or the environment he was in made him succeed) usually underestimating the person's personal actions.
