The article in no way says that being a good programmer is sufficient to become a billionaire. It states that there were long-shots and coincidences that led to Bill Gates's stellar rise as Microsoft's founder, beyond his programming and business skills (It's not denying that his programming and business skills didn't contribute). The article states that, in competitive contexts, many have merit (programming + business skills, in the context of Bill Gates), but few succeed. What the article is effectively trying to say and the point you seem to miss is that, the the link between merit and outcome is tenuous and indirect at best.
