At least as far as the term is used in gaming, a "drought" implies more than just not getting a certain desired game or series, it's more used to denote a severe shortage of software in general, like say most of Wii U's life, or the twilight years of the Gamecube and Wii.
There was very little for me personally in Switch 1's 2018 for example, but I wouldn't say it was a drought as it did still get plenty of releases I may not have really cared about like Smash Bros Ultimate, Octopath Traveler, Dead Cells, Undertale, Hollow Knight, Dark Souls Remastered, Diablo 3, etc.
