Yes, anything that makes your brain secrete that happy chemical will lead you to get addicted or obsessed on something, that's why drug addicts do it, they get so happy and their brain is spiking in terms of that happy chemical and when they get down, their need for it gets so dire that they have to do it again and again until the size of their addiction to satisfy what happy chemical their brain is craving is so colossal that it's difficult to cure or rehabilitate the habit and the way out of it gets narrower by the day. Remember the old adage, anything in excess will almost always lead you to problems, excess money? More problems with taxes and fake people in your life, excess lovers and you'd never find the happiness you're looking for when it comes to finding a companion.

Someone who isn't a regular and aggressive gambler cannot do something like that. If I'm not a regular gambler, and I barely make a bet or two, and if I'm invited to a get-together where we have to play friendly and non-gambling games, I wouldn't do anything like that because I wouldn't have that thing in me that would keep tickling me to become aggressive and start making arguments and take everything very seriously and make the environment tense.

What he did shows that he is either already a gambler or he has a very aggressive nature because you will also find people who are naturally aggressive to do things like that no matter what they are doing, they get serious in almost everything they do even if it is a friendly game being played among friends.
