To a point, sure. Same for things like spell points or slots, and magic in general for all that: it's real in the setting, and the spell slots or points (and the martial powers) are simply different ways abstracting those setting realities into game-useful things. The perceived or real usefulness and quality of said abstraction varies, of course, depending on the user and-or observer at the time; hence many discussions here.
I think the meta/not-meta difference lies in which "direction" it's going: if you're taking an in-setting element and somehow abstracting it, it's not meta (which covers the Force mechanics in SW), but if you're taking an out-of-setting element (it's Joe's birthday today so I'll give his character +1 on every roll tonight) and adding it in then it's meta all day long. Pretty much every mechanic I've ever seen that gives or allows a die re-roll after the result of the first roll is known falls into the latter category.
