Oh of course. It is a learning curve to find the sweet spot of "Sure you can do that" and "lets roll the bones on it". However they do give a good baseline in the alternative rules section of the Edge of the Empire book for Passive checks. It isn't perfect, but it can give a good baseline of "this isn't super important, can we skip it?" and "The fate of the galaxy rests on you hitting that target no bigger than a wamp rat". As well as the various stages in between.
That said, there is a large amount of confirmation bias in dice games as a whole (not just limited to RPGs, listen to a craps player descibe the "real" odds sometime). And failures can be hilarious, and frequent. Just listen to all the times Bacta (the medic) on "The Campaign" podcast fails his medicine checks, even though he is pretty darned good at them, while Tristan seems to beat the odds no matter his roll lol.
