I hope you're being sarcastic
Not really. The most common definition of "casual" is indeed a game that isn't liked and that's basically what can be infered from your original post. The comparisons you draw include 1-2-Switch and Labo, and the closest you come to defining a casual game is the pick up and play trait. Said trait is fundamental to Mario Kart, but that game is suspiciously absent from your original post, so it's fair to conclude that your definition of "casual" includes the trait of being a title that is in general considered a lesser game.
