She is an outlier in the sense that she is both “new money” and also “old money” (she did the equivalent of inheriting money in her settlement with Bezos).

She was, at one time, a normal person, with normal friends and normal parents. However unlike most other “new money” billionaires she acquired her wealth without the corrupting influence of being a master of the universe business person where everyone in your circle is falling over themselves to gas up your ego.
