Sure, StarCraft is kind of a hybrid when you think about it. The guaranteed-hit model, the extremely simplified low vs high ground approach to determine if a shot is possible, etc. are pretty deterministic. But in more complicated situations it's still a lot less predictable than chess. Even the examples you're giving can only happen probabilistically outside very early game.

But I'm thinking about TA-style games, the topic of this discussion, which pride themselves on large armies. Though, to your point, early game of Supreme Commander is also quite chess-like, because of how restricted the set of opportunities is.
