Well I mean Errol quite literally funded his first company.

But also, Errol had a very successful engineering business. There's no question that was a huge influence and advantage to Elon. He got an informal exposure to engineering at home that would be better than the universities available in some impoverished places.

The evidence for grit is nonexistent. What correlates most strongly with successful entrepreneurship is having upper middle class or better parents. This is because they provide a better education, literal seed funding, and if nothing else, allow someone to take more risk knowing they won't end up homeless.
