Bonjour Lisa !

The meaning is indeed there, however "je sens la rose" is a figurative expression, which you wouldn't really translate by the plain equivalent "I smell good", but by a similarly visual image (like heaven, like roses...).
The neutral way to express "I smell good" is "Je sens bon" :)

In the same way, you would translate "it's raining cats and dogs" by the simple "il pleut", but rather the equivalent colloquial expression "il pleut des cordes".
Bonne journée !
