No, it is not mandatory by European law. The myth persists.
The site can use essential cookies or no cookies just fine, with no banner required at all. Nothing.
If they decide to use non-essential cookies, for example privacy-intrusion tracking cookies to follow your activity around the web for advertising, then they need to notify you of this tracking and obtain consent. You have a right to know, after all, and you might prefer to exercise your rights by declining consent. But nothing requires it to be a large banner, and nothing requires the "reject all" button to be difficult to find.
