I feel like gambling pattern 4 is what turns gamblers into addicts. When you gamble and complete one pattern mostly its gonna be called luck (by yourself of course). Give in enough time so you will one day do epic comeback for sure. It may take days or it may take years! But it will happen. And your brain will quickly consider it a epic comeback that shows your skill. Your chemistry will force you to play more and more. And you become typical gambler.
Gambling pattern 4 can turn a gambler into a gambler, which is what most gamblers have experienced. And remember that luck will not always come to you, so you don't need to chase more wins or try to recover losses you have experienced. But if you are trying to use more money to chase more wins or recover losses, it can turn you into a gambler addicted to gambling. The desire to repeat winning will keep coming without you being able to hold it in and that's when you will experience bigger losses.
