Going back to the point raised at the beginning: I believe terms like 'probabilities' and 'uncertainties' are terribly unhelpful because they lead your thinking towards the mystical domains of "inexplicable randomness", paradoxical dualities of particles in existential crisis, spooky non-local particle conspiracies and "a consciousness observing a particle makes it behave differently", all of which seem like strawman takes, but they really aren't.
Some of the greatest physicists we've had have been known to struggle with making sense these questions because of the cultural biases they spawned into, and really, just read or watch almost any pop-science media and you'll be presented with these "paradoxes" - usually accompanied with "we just don't knoooow" because humans have such a hard time giving up on certain things that don't jive with observations (consciousness, free will, 'physical' reality, clearly defined and absolute answers etc).
