Cortez talks about nearly winning the lottery by getting four out of five numbers. But the Powerball lottery he was playing involves six numbers, five regular ones, plus a sixth "powerball" number.
Cortez explains the moral of his story where he got four out of five numbers of the Powerball lottery as being about the binary nature of reality: either you're a winner or you aren't. But the Powerball has lesser prizes for partial matches of numbers. His four numbers would have won him a prize.
