Another way to operationalize this difference you called out at the end is by saying, counterfactually if I were sufficiently motivated to do X, I would do it. Of course this leads you just as dense a philosophical thicket, just moving it to the nature of counterfactuals rather than the nature of will.
But in some ways your conception of the problem is also too narrow because it seems to partly include a distinction between muscle skills and cognitive skills? I am not “able” to beat Magnus Carlson at chess but it isn’t because I’m physically unable to move the pieces appropriately.
