Do Electrons Actually Move Around in Resonance?

So in school (I'm in high school), we were taught about the resonance effect, and from what I understood from my teacher's explanations, the molecule keeps changing structures. That is, the electrons keep moving around the compound?, like in Ozone, the bonds keep alternating for each pair

But what I understand from the formal definition is that the molecule only truly exists as what we represent by a resonance hybrid and that electrons are "delocalized" between atoms

So, do the bonds/charges/lone pairs actually alternate in resonance? I'm super confused about this 😭
