I'm not sure it misses the mark. All data show that wealth carries over multiple generations. That doesn't mean that non wealthy can't make it, just that wealthiest will, on average or even probably some p95 and up metric.
And wealth should be put into perspective, its often more to do with the surrounding education of the wealthy. If your surrounding growing up ran businesses of their own, knew how to manage people, understood finance, investments, calculating risks, knew about markets and business, had connections, that's a great environment to learn the same from. You mentioned both your parents had technical university degrees, so you had some advantage there.
Everyone can give it a shot, we have equal opportunity, but not equal challenges to face. You making it out of less is double awesome to you, even if maybe you felt it was easy, dunno, its still a hard thing you did, harder then if you had come from a more supportive environment.
