I think I get what you mean, but we should be clear—every measurement is probabilistic, right? We can measure photons with low enough inaccuracy that we don’t bother quantifying the probability that they might not exist. But, it is actually on some philosophical level a difference of degree, not type. I’m pretty sure.
What does it mean for a measurement to be probabilistic?
I'm a math grad student, so still a layman, but here's the way I think about it: Every particle travels over every possible path as the wave spreads out. Once you measure the particle, it tells you a path.
So the measured value of the particle is probabilistic, not the measurement.
