Yes, it’s like what we say in relationships, love is sweeter the second time around. He was already addicted before, and since he quit, when he came back, he became even more aggressive because he already had the experience. If he returned to gambling, it’s either he was in a desperate or worse situation in his life. That would explain why he’s more addicted the second time. Maybe he felt he had no other options left but to take the risk again, even knowing how slim his chances of success really are.
