Given that the most well known story of a prophet predicting a flood involved him building a boat, that doesn’t sound like anything particularly insightful.
I think it means that Prophets aren’t worth taking seriously unless they are staking their own reputation, well-being, or money on what they predict. There are many people who claim to know a particular thing for certain but who curiously aren’t putting all of their own money on it. A perfect example probably being people selling stocks and investment plans.
