It appears (unless I’m mistaken) that when you hover the mouse cursor over an enemy unit in game, it doesn’t even tell you what the unit is. I know that there is a place in the game that lists counters, but in game, I have no idea what unit is actually what. For example, I have no idea what the counters are (and unlike games like Age of Empires, where I can at least use history as a rough guide, I have no idea what Protoss shiny thing is supposed to counter a particular Zerg blob thing). But it seems like it is intentionally daunting.
