Beginner’s luck refers to the initial good fortune or success commonly supposed to come to a person who has recently taken up a new pursuit. The supposed phenomenon of novices experiencing disproportionate frequency of success or succeeding against an expert in a given activity.
The term is most often used in reference to a first attempt in sport or gambling, but is also used in many other diverse contexts. The term is also used when no skill whatsoever is involved, such as a first-time slot machine player winning the jackpot.
Even if you’ve only gambled once or twice in your entire life, you’re probably familiar with the expression “beginners luck.” It’s a common belief among gamblers that players who are new to a game will always win.
