Everybody tells that to investors. Legal boilerplate. Doesn't mean the executive ego and hubris doesn't blind them to reality.
Anyone who deals with the money knows it's the truth. The ones who choose to ignore it are the ones for whom the money just shows up. But if you're one of the people involved in the exchange of money, you know it's a crapshoot. And you know why. For the same reason as owning a restaurant is a crapshoot. Or starting ANY business is a crapshoot. And sure you want to put on the confident appearance. But inside, you know the reality.
