I bet they do. One problem, that most people in this thread are missing.
Gambling is still illegal in the US.
On that point, I agree that it should be legal. I’d love nothing more than to see a privately run casino bitch slap the Seneca Nation back onto the rez, and see US corporations running online gambling sites with tons of money going back into the tax base. But that one little sticking point… gambling is illegal. Want to solve this problem? Get organized and push for legalized gambling. Face it, anything short of legalizing it is just exploiting a loophole, which it is the government’s responsibility to close.
