The description was incomplete. The cour de cassation is not supreme at all, there are the Constitutional Council and the Court of Justice of the EU above it. As well as more specialised international courts like the European Court of Human Rights. There is a summary here: https://en.m.wikipedia.org/wiki/Judiciary_of_France https://en.m.wikipedia.org/wiki/Judiciary_of_France . In any case, France has a civil law system; there cannot be a court as powerful as the Supreme Court of the US is. Viewing any of these institutions as similar to SCOTUS is bound to create a lot of confusion.
