No, particles are particles because they deposit all their momentum into a single location. The states are modeled as mathematical functions, special mathematical functions known as wave functions. The wave function encodes every thing that can be possibly known about the particle (this is why you have to change/collapse it when you learn more!). It is not physical thing (at least by Copenhagenist), it is a bookkeeping device. Not unlike a company’s financial records. Don’t confuse the company for their files. Don’t confuse a particle with the mathematical object we use to store its details.
