As there's always a risk behind and those who understand the risk and knows how to manage their emotions mostly have that opportunity to enjoy, some might have that chance to earn decently.
Yes and that is the main reason why games have to be made for people of legal age, so that they will be able to face things, the responsibilities for Everyone , then in view of this we can deduce that all the time we have the final decision, the risk is something that we must risk, but the risk is Determined by us, not the casino, the casino is simply the receiver of that risk and Transforms it into a game , into randomness, into luck for the player taking into consideration the house advantage.
The casino is not forcing any gambler to gamble more than he can afford to lose. But sometimes I see people blame them for their losses. If you observe that you are not emotionally mature to control how you place bets, it will be better to shun gambling. As adults we should take responsibility for the outcome of our lives and quit the blame game. Gambling could be fun if you understand that it is based on luck, that is why we should play it with caution. Gambling is not necessarily for the strong hearted but for those who have self control.
