This is completely false. You need permission for any data you store on a user device or retrieve from a user device if that is not strictly needed for the execution of the service the user requested. Nowhere in the law is the word "cookie" even used, so your suggestion that "1st party cookie" is different from "3rd party cookie" is wrong. And similarly, this whole thing also applies to all alternative tracking methods, so you cannot avoid it by using localStorage for example.
A 1st party tracking solution is in no way considered needed to deliver the service the user requested. Only things like remembering my shopping basked are necessary to deliver the services of a webshop. And you cannot use that cookie for other purposes (like counting visitors).
