By "skill" I'm referring to something far more fundamental, perhaps trait would have been a better word. For instance sports are largely about athleticism, hand eye coordination, strength, and so on. And these all are largely transferrable. Similarly in mental domains I'm referring more about the ability to accumulate and process information while also using it as a tool think more outside the box, than as an ends in and of itself.
Are you saying that a rifle shooter could easily pivot to darts or pool, and a swimmer could just as easily move to baseball? Or a body builder could take on a rock climber because they are in the domain of "Sports"?
All sports have different muscle memory training and thought processes.
