I don’t think I’d call Deleuze “wrong” based on my one line description, if you haven’t read him yourself. The rest of your comment seems predicated on a Platonic idea of concepts; which is definitely not in line with how Deleuze thinks about things. His ideas are very much not in line with the typical way of thinking about concepts as universal things we discover. Edit: I should note here that I’m not an expert on Deleuze or Platonism, but I would probably say that Deleuze’s skepticism makes more intuitive sense to me.
