People always state things like this to imply "it's not what you know, it's who you know." I think it's quite the opposite - she grew up in a family environment where the fundamentals of business were part of the culture, as much as literacy and education.

If a kid grows up understanding finance, business development, how to pitch an idea to investors etc. they're going to be lightyears ahead of some kid who grew up being taught to 'do well in school so you can earn a good hourly wage'.
