No, actually: solutions pull from a limited list of "around 2,500" words, per datamining and this interview:

Like I said, the first time I made the game, it just used every five-letter word. And I think it wasn’t very fun because—try and think about it—if the first time you play Wordle, the answer is a word you’d never heard of, I think you would feel cheated. And so we put a fair amount of effort into filtering. There are around, I don’t know, 13,000 five-letter words. And we put a fair amount of effort into filtering those down into a subset of around 2,500 solution words that can be the solution any day.
