Even a genuinely deterministic system will be perceived by a subset of that system to be unpredictable and random.
Constructing a perfect model of the universe within the universe is logically impossible. We can't ever rule out an irreducible uncertainty. So we really have no reason to presume that the universe contains random elements, and we have no reason to presume that it doesn't, either.
That would seem to carry QM implications that sound very much like you're suggesting that QM does not imply an indeterminate result for each individual interaction, seen from the point of view of this universe. If it appears random from inside this universe, modeled or not, then from our point of view, there is irreducible uncertainty, even if in some uber-universe the gears and wheels are easily observed.
That clockwork may exist in a bigger, more inclusive universe, but we can't see it or observe it, and that's what QM seems to quite definitively say about OUR universe, the one we live in.
That would say that as far as WE can tell, regardless of model, or actual systems OUTSIDE this universe, what we observe *inside* the universe appears to have irreducible uncertainty. (BTW, I like that term as opposed to 'random'.) From our point of view, trapped inside this universe, THIS universe has irreducible uncertainty, then, yes, even if it's not irreducible in the uber-universe. If you're arguing otherwise, I think we need to get some discussion with the QM folks here going. Tez, are you listening in?
If we can never observe the mechanisms that create the uncertainty, but they exist, well, yes, that's an interesting statement indeed, and that would then create very interesting questions of the origin of the universe, as well.
On the other hand, if probabilistic behavior is all there is, we have very little trouble, eventually, having the universe exist. Then we have to ask 'why is that the actual way it works', and that's a question for another day altogether, indeed. One could propose the answer is "because" or even "that was probabilistic", but determining the truth value gets, well, complicated, eh?
