aiui, professional physicists don't think particles are "real" but a phenomenon that appears as a result of attempting to localize a wavefunction through a measurement
You seem to be arguing an old version of pilot-wave theory, which has a version that's wrong (because it predicts real life incorrectly) or isn't known to be wrong but isn't falsifiable either (because it predicts real life exactly the same as QM). It also doesn't work well with special relativity, so it's less correct than QFT.
what is the reality then?
when you get down to those scales, there really does seem to be uncertainty when you try to localize parameters. on one hand it's troubling but it's also lovely because we get stuff like the casimir effect, and who knows what other futuristic technology we might end up making, which we all want
There's a viable alternative to this called "superdeterminism", but it makes everyone in the world except Sabine Hossenfelder unhappy if you bring it up because it's even worse than telling them they don't have free will.
