This is a philosophical question and can be subjective to interpretation. Some people believe that luck is a matter of chance, while others believe that it is a combination of preparation and opportunity. Some may argue that luck is simply the result of cause and effect, where our actions and choices lead to certain outcomes.
Others, including some philosophers and scientists, believe that luck does not exist and that everything that happens is determined by laws of nature and causality. In this view, chance and random events can be explained by underlying causes and patterns.
Ultimately, whether or not luck exists and what it means is a matter of personal belief and perspective.
