I'm surprised Jagex doesn't introduce another gambling feature to try to capitalize on it and make more money (other than sof). Any kind of gambling mechanism that requires people to pay real money is always a profit because you can rely on addictive personality people with lack of self of control to spend out of control. Jagex should just create in game "casinos" which do dice, flower game, seal, horse game etc all requiring in game payment in order to pour more money into jagex.
