I realise it's not as obvious as poker, and I understand that poker is actually a pretty good metaphor for business in some aspects. But luck in poker is governed purely by probability, and we can calculate that. In business, where's the luck? Being given a million by Daddy? That's just like a poker player learning how to play at the macros instead of micros. You still better start winning soon.

If he bought into one company at the right time, and had no actual influence in the decisions that led to its success (or indeed potential failure), then yeah we can say he was lucky. But if he is directly involved in the business decisions, and in multiple companies, well each decision is a hand in poker, and for a business to be successful, it needs to make net +ev decisions.

I have no problem with half a decade of business decisions being put into "career" territory, rather than "casual".
