I can give a very simple explanation of how luck is a part of the equation of success for anyone who has ever been born. The distribution of opportunity is clustered in certain locations. It is not even.

To be born in a country with equal opportunity, libraries, free education, water, electricity, non dictators. That is lucky.

Wealth arguably follows a log normal distribution. This means all the benefits combine multiplicatively, so that even seemingly small differences in the positive will combine to give a substantial advantage.
