I was always confused with the Gamblor/ Lord Gamble comments - but most originated during his time at Brisbane and were quite prevalent on Reddit.
Saw a few comments over the years try and explain the origins, however, like most of the internet, trying to find a serious response is tricky.
A few explanations:
Lord Voldemort - there were a few references to Gamble for presumably looking like Voldemort. Or because he was a master of the “dark arts”.
Some referred to him as Voldemort. So I can only assume that the next step or related step is to refer to him as Lord Gamble.
Gamblor - Simpsons reference. The god of gambling or the god of random events. Could merely be a reference to his surname, his gambling habits or the “totally random” (said in a school girl voice) way he could affect a game positively or negatively - a roll of the dice which one.
I then think a few cottoned on to the Lord Gamble reference, a few did not and thought it was a bit of a cult reference that some section of supporters saw him as a saviour for their form.
Regardless, I think the origins of both references are not seriously considering him a “god” or “lord” in a serious, positive way. More tongue in cheek.
