>So, does this mean that this explanation for Quantum mechanics https://www.youtube.com/watch?v=WIyTZDHuarQ has been vindicated?

If anything the virtual particles are an alternative to the pilot wave theory. Instead of having quantum effects mediated by virtual particles the pilot wave theory uses a 'pilot wave'. Now as far as I know most phenomena caused by virtual particles can be explained by the pilot wave, but I'm not sure how easily.

Either way, results like these which seem to be in favour of the existence of virtual particles are weak evidence against the pilot wave theory.
