The other responses to this copy/paste response are spot on. Software developers don't produce "original work" when it comes to the actual code, our originality and creativity comes into play when we put all the constructs together into a solution to a real problem. You're treating Copilot's suggestions as paragraphs or pages of a work, when they're more akin to words and short phrases; it's not plagiarism to use other people's words, and it would be utterly daft and counter-productive to avoid using others' code or require each and every developer to reinvent the wheel at every turn.
