Normal people (like the majority ones around here) won't ever have the opportunities/skills/luck all combined at a given point in time to generate billions. So any advice from his side regarding money is simply misleading.
This is pessimistic and cynical. Many millions of people are capable of succeeding if they strive for it, and in doing so making better lives for themselves and others. Hearing words of encouragement, useful advice, and inspirational examples from those who've done it can be tremendously motivating, and is often the difference between trying and not trying. Between "I did it" and "I wish someone had told me it was possible."
