Gambling is an activity in which people place a bet on an event with uncertain outcomes. It can involve many types of games and events, from lotteries and horse races to online casinos and pokies. It can be a fun way to pass the time, but it can also lead to serious harm and financial difficulties. People can be addicted to gambling, and it is important to recognise the warning signs and seek help if necessary.
There are a number of things that can affect whether someone develops harmful gambling behaviour, including mood disorders, substance use, coping styles and social learning.
