To be honest mate I still don’t understand how gambling works. I understand the fundamentals of gambling, especially the maths behind poker etc. But sometimes I know i should walk away from something but I just keep going.
So to answer your question, some of my mates have no idea about gambling but in the same breath I have no idea why I used to make some of the decisions I used to do regularly.
In your case, I would have stuck a quid in as well though
