Think of the Monty Hall problem. According to the lines just above those, those 500,000 selves have greater probability mass than the 3 red selves. But then combining them, you have a single green self with a greater probability mass than the single red self.
For the other part, see The Anthropic Trilemma about the Quantum Lottery thought experiment.
