It also matters a lot what type of uncertainty a game has, and what the curve of learning to manage it is.
E.g. slight variations in inputs should produce a slight but ideally meaningful variation in output, so the outcome of pressing keys is both reliable as well as an open space for further mastery.
It's also important that you can trace and understand what happened in retrospect. Just missing because of a 5% chance isn't fun. Missing because you didn't consider wind direction and the movement of an object between you and the target on the other hand is perfectly grokkable.
