If we can limit the budget, obviously we will play gambling well controlled without big ambitions to win big, use a healthy mindset to gamble for fun even though it uses real money, always use unused money and prepare money that you can afford to lose that, don't use any strategy because it will be useless, the dealer will always win, just control yourself until you are completely satisfied and get a win then withdraw it. don't make it your main target. just enjoy the game
Another thing is understand the game, like you stated one could try with a demo account to understand what they're getting into, they're many casino games that looks easy but you'll find people loosing because they didnt take their time to study the game but just rushed to play based on assumption that they're already familiar with it or have little ideas, it's best to take a while to study the odds, be strategic and study the probabilities of having less lossess be gambling.
