Gambling is the act of wagering money or valuables on uncertain outcomes, often in games of chance or skill. It encompasses a wide range of activities, from casino games like poker and roulette to sports betting and lotteries. While it can provide entertainment and the thrill of potential winnings, gambling also carries risks, including addiction and financial loss. Responsible gambling practices, such as setting limits and recognizing warning signs, are essential to ensure that it remains a fun pastime rather than a harmful habit.
