For me i think they are already getting royalties from casinos and sport bookies because every day we see events hosted by this sport leagues sponsored by different sport bookies and casinos, using BC.games and Stake.com as example you can see them in almost all sport leagues advertising and paying them so that's a special benefit the sport leagues already get from them.

It must not be so clear or like taxis before we know that they are getting some little royalties for the role they play i  thr continues business running of different casinos. We may not even know if those payments that casinos and sport bookies pay before they start operation or get licence might even go to sport leagues too.
