I challenge you to find a website that will let you charge $10k into an online gambling account from a credit card. And any that do exist will charge fees higher than credit card rewards in most scenarios.

But yes, you also will not earn points on balance transfer transactions. But they typically are processed via ach.

You're right, I haven't tried to deposit more than about $1000.... however I could just do that over and over again.

With a credit card? Which site? To my knowledge this did not exist. Discount fees would cost them 2% at least.
