Your first win will trigger the hope in you that you can win again. This will make you continue gambling even if you has a losing streak after your win. I have said to myself that I wouldn't gamble again but after two weeks, I decided to bet on a match for fun. Surprisingly, I won my bet and that was how I started gambling again.
Some new gamblers are lucky to win their first bet, and that will make them feel that it's easy to make profits from gambling. This can misled them to start gambling thinking that it's a means to make a fortune.
