Not magic that is useless to society.
Magic that is not valued by society.
So like just like academic scholars?
Hmm… In school they would be taught some magic that is not really useful but that “has pedagogical value.” At work they’d be forced to use the magic that the market demands, but it’d be unimaginative and micromanaged. But they would have some hobby magics that are very amusing but slightly embarassing…

Yeah, in a world where fire magic existed, there would be fire magicians whose day job was being a human-powered blast furnace, blasting something with fire over and over. They wouldn’t be out having adventures, and the use of their magic would probably be heavily regulated.
I would spend so much time trying to perfect liquid luck
liquid luck is basically cocaine though
