@Ceiii2000 - Mostly correct, yes.

The problem and the reason they're non-sterilizing is that sterilizing immunity comes from the "N" protein and mucosal layer in your respiratory tract. The spike has evolved to evade that recognition in coronaviruses generally, so if you look at an antibody profile of someone who was infected and recovered you see much higher "N" protein recognition than "S", and the protection is heavily-skewed into the mucosal layers.

The jab produces only "S" protein antibodies and distributes them all over the place via the circulation (along with the spike itself), with a focus in the endothelial layer of the circulatory system (since that's where it all winds up originally.) This is wildly wrong compared with where you want it, but it does inhibit systemic effects of the infection. Unfortunately it does nothing -- or very little -- to prevent infection itself. We deliberately did not test for other than symptomatic infection during the trials, and have studiously avoided tested jabbed people since unless they got actually sick. They knew damn well that the jabs were non-sterilizing and had they looked and presented that it likely would have precluded a broard EUA from being issued in the first place.
