Yes exactly - "free will" is shorthand for "There's a mind with subjective experiences involved in all of this, and we have no idea what that means or if it even means anything."
We don't know what minds or qualia are, and until we know for sure - as opposed to hoping and guessing and "well obviously..." - these speculations are just hand-waving.
The problem is that all of physics is filtered through our minds. We literally have no way to experience reality without experiencing it through a human mind.
So although we've managed to persuade ourselves our experiences of science are "objective", all that really means is that other human minds are very likely to have similar experiences if we set up similar circumstances in similar situations.
Potentially our minds could be operating in the conceptual and experiential equivalent of the visible light spectrum, and the range of possible "objective" experiences is very much wider.
