No, GP means (in the second line) that because nature (and particle colliders) perform so many "experiments", even very rare outcomes will be spotted eventually.
It's a statistical statement about many particles (or field-values in a sufficiently large spacetime(-region)-filling set of quantum fields), not an interpretational statement about a single particle.
