Not really sure if I have commented this topic before, but I'll take the 1st criteria to comment:
a good gambler never chase profit
Profit might be the first reason why people gamble, but a good gambler never attached to the profit, the most important thing in gambling is excitement and fun experience, having profit is just the bonus
If you think that good gambler never chase profit, means that all gamblers in this world is not good gamblers.
All gamblers are chasing profit, this is why it is called by gambling where gamblers risk their money for more money.
It is bullshit if gamblers are gambling just for fun and entertainment only, if they just want to catch the fun, they should not gamble with real money as they can use demo mode.
I would prefer to say that good gambler is not about what they chase, but more about how the chase it.
