yes,
and further....

one way of looking at this question.. is...
that when we measure or “ask” for more specific information (such as an “electron’s’ (or any quantum entity’s+ “exact location” from within the range of possible sites that Quantum physics predicts it MAY be at...).......
that the ‘system’ responds to us/our measurement effort.. by “answering” with one of the predicted/permissible answers/locations/sites

this is sometimes called the “collapse of the wave function”...but that is easily misunderstood.........
the wave function was never a statement of where the quantum entity was....and the wave function never said that the quantum entity was spread out over a range of sites or an area..............
...the wave function was only a prediction of the range of locations whereat our future measurement might find it.....(with probabilities for each location)..

insofar as quantum physics (Schroedinger’s equation) is concerned, the maths never said exactly where the quantum entity/electron was located.....and never tried to...it gave us no such information about anything....it does not describe the present reality....it merely predicts the odds of the results of our future measurement

in other words, consider one horse on a race track. Schrodinger’s equation does not tell us where the horse is presently on the race track. Schrodinger only gives us the odds on one characteristic of the horse in the future when we measure for that characteristic....
say, we “measure’ for the time of the horse’s arrival at the location of the finish line (maybe we watch.measure for his arrival at the finish line with a stop watch)......Schrodinger’s equation predicted for us the range of the horse’s arrival times... with probabilities for each possible arrival time.

So, we could say that Schrodinger is a bit like an race track oddsmaker or tote maybe....but the key idea here is that Schrodiner and Quantum physics do not attempt to tell us where the horse is on the track at any present moment, they only predict the odds of each of his possible finish times.

re: “ from within the range of possible sites that Quantum physics predicts it MAY be at”

QM, just one big “curve fit”.

Where’s the “predictive” capability in that? And the reason science has stalled out, QM has an erroneous basis ... no basis on “first principles” such as electromagnetics (Maxwell) for instance.

And the probability, in QM, that ‘coffee’ could exist outside the ‘cup,’ is greater than zero.

It’s called quantum tunneling and Luddites who declaim the absurdity of something so counter-intuitive are left to explain the successful application of quantum tunneling microscopes.
