Because they are stating this story as something negative, some drawback. Perhaps it is, for them, but that's where the context and perspective should come in. To me it sounds like an incredible success story. Most people I know, me included, don't have any of those things, although some are well on their list of goals. Having achieved all of them at that young age is a privilege, maybe also due to privilege (I don't know), but certainly not a burden or drawback.
