Gambling

Gambling is risking money or something valuable on an uncertain outcome, usually in the hope of winning more. It includes games of chance, wagering on events, and other bets.

Probability: Probability is a mathematical measure of how likely an event is to occur. Every wager turns uncertain outcomes into chances that can be estimated.
Casino: A casino is a venue where people play games of chance and skill for money. Casinos gather table games, electronic games, and wagering under one operator.
Gambling disorder: Gambling disorder is a persistent pattern of gambling that causes significant distress or impairment. For some people, repeated wagering develops into a clinically recognized disorder.
Insurance: Insurance is a contract that transfers specified financial risks from an individual or organization to an insurer. Both price uncertain outcomes, but insurance protects against loss rather than seeking a wagered gain.
Expected value: Expected value is the probability-weighted average of the possible outcomes of a decision. It shows whether a bet pays less or more, on average, than its price.
Sports betting: Sports betting is wagering on the outcomes or events of sporting contests. It applies odds and stakes to real-world competitions.
Problem gambling: Problem gambling is gambling behavior that causes harm to a person or others, without necessarily meeting diagnostic criteria. It captures financial and social harms that can occur before or without a disorder diagnosis.
Investing: Investing commits resources to assets or ventures with the aim of earning returns over time. Investments can be risky, but typically involve ownership or productive assets rather than a wager alone.
House edge: The house edge is the casino's average mathematical advantage over players in a game. It explains how casinos can profit over many wagers despite individual wins.
Lottery: A lottery is a game in which prizes are allocated by random draw among purchased entries. Lotteries turn many small payments into a chance at a large prize.
