The note 3 was 151.2 x 79.2 x 8.3 mm

The iPhone 17 is 149.6 x 71.5 x 8 mm

So no, the note 3 is bigger than the iPhone 17

But, and this is probably what you meant, the iPhone 17 has a bigger screen. That's because recent phones got rid of the bezels, so they can fit more screen in the same body. That's why they have taller aspect ratios.
