Not joking at all.You must be joking?
I myself got O from a vax’d and boosted friend. Everyone in my office is vaxx’d and all but 2 people have gotten O at different times since the holidays.
Everyone in my peer group is Vax’d. All but 1 have gotten O in January.
Unvaccinated people may be uncommon in some places, but they make up a large fraction of currently infectious people.
For SCC, unvaccinated are 15% of the population. But they test positive at almost 6x the rate of everyone else. The net effect is that about half of all new infections are unvaccinated people.
Then remember that vaccinated people spend less time at peak viral load. With that, more than half of currently infectious people are unvaccinated. Far more than half if you live in a county with a lower vax rate.
Given that, it's entirely possible you and your friends got omicron from unvaccinated people who just happen to like the same bar, restaurant, coffee shop, or gym as you do. There are lots of infected unvaccinated people, you enjoy indoor establishments, and omicron is very contagious.
That is not proof or even close, but it certainly isn't obvious the other way, either.
