Before her amiibo card was released, Judy was considered a rare villager. But so was any villager who couldn’t simply be scanned into the game. Now she has her card; she doesn’t seem so rare despite the odds of getting her card from a pack remain very slim. But, of course, she’s much easier to come by in terms of players willing to trade when she’s moving, so I’d say she’s nowhere near as rare as when New Horizons came out!
