I’m not sure how you took this from what I posted. I was surprised Viking couldn’t find even a table for two for the OP at either restaurant, at any time, on any day of their cruise. They need to do better, and I hope they accommodate the OP.
But you do raise an interesting possible loophole. Viking guarantees reservations at each specialty restaurant, but I don’t think they guarantee that you won’t be seated with others. That said, I don’t think I’ve ever heard of someone being forced to sit with others if they didn’t want to.
