Come to think of it, im not sure where it comes from either. I've just heard it stated many times on the Internet, and the Internet never lies. The reason I asked is that logic tells me that if you are earning a regular sizable income from gambling, the taxman may want his cut. I've also heard of certain pro players 'officially' running a business to avoid any tax issues.

Some pages of interest i've come across, though nothing that convinces me 100%:
