My point was that you're kind of defining luck as a form of opportunity, which is itself a product of chance. I think maybe you're just describing luck in different terms without altering what is meant by the concept.
Well luck is usually thought of as favorable chance occurrences, usually as a way of rationalizing why some people have success in some area and some don't. The argument is that this form of "luck" doesn't exist. Certainly chance occurrences are a part of reality, and some of those happen to be favorable for some people. But ultimately "favorable chance occurrences" isn't a good explanation for the observed disparity of success. What is a good explanation is chance occurrences plus preparedness. And so what we generally refer to as luck is really better understood this way.
I don't think the meaning of concepts are the types of things studies generally shed light on. It's just a philosophical argument. Feel free to accept it or not.
