Starting positions are also randomized and the maps are not symmetrical (nor are Terran buildings with add-ons!) so starting position matters slightly. Plus the balance tweaks are somewhat aribitrary so there's a degree of luck to when exactly a match takes place. I'm sure there are many more examples of non determinism but the biggest differences to chess are hidden information, which makes it resemble poker, and real-time actions, meaning SC is a game of dexterity as much as it is a brain game.
