The Steam Deck has sold only 4 million units in 3 years, which is a rounding error in the console market, not a huge success. The Switch 2 has generally been considered a failure (due in no small part to a serious lack of interesting exclusives at launch) and has still sold more than 10M already, while the Switch sold 154M units and the PS5 has sold 84M.
