Luck in gambling is only temporary, therefore it is not surprising that the money earned in gambling will return to its original place, or in other words we will be in a cycle called addiction. In my opinion, the fundamental difference between beginners and experienced gamblers lies in the control of their emotions and actions, understanding certain types of games really depends on a person interest, while the chance of winning can never be measured with certainty. In some places gambling is indeed legal, but in other places gambling activities are strictly prohibited and taboo, due to cultural background, religion and state regulations.
I think whether it is a beginner or an experienced gambler, it is appropriate to hide their gambling activities. Because from a social perspective, it is seen as a complete contradiction to ethics even though the state legalizes it, especially if the gambler is a person who has a position or influence in the social environment. Associating with an environment that has an interest in gambling will indeed influence someone to try it, very relevant to this wise saying "social relations determine the direction of the future", only a few people are lucky in gambling.
That's right, luck is only temporary, the essence of gambling is losing money, therefore we as gamblers must always be careful in every action we take. and I agree with you that what differentiates fellow gamblers is self-control and the actions they take. If he is in good control then he is a responsible gambler, whereas if he is out of control then he is a gambling addict. And it is true that it would be better if we covered up our gambling activities to other people because it is not certain that other people will be able to accept our activities.
