Honestly, for some people money is not everything and if gambling games are not entertaining then they wont bother worrying about money at all. Just look at the games that one can play in casinos. Roulette, dice, poker, slots all are a way too boring. It may keep someone interested for a day or two but these games cant entertain us for long.
Probably you must be wrong. Gambling has some big differences from games. The involvement of money makes those huge differences. Any game or any entertainment activity definitely will bore you at some point of time but when you are having the hope of making easy money then you will never find those activities boring you. This is what happening with gambling and we are all seeing that all the gamblers are enthusiastically still going for gambling activities even they are making big losses with it.
I am just talking about the general mindset of most of the gamblers because there could be many exceptions everywhere. If gambling will bore us after some point of time then probably gambling industry might not have been surviving till now.
