Evergreen was just stating something that was a common prejudice about Celestial Spirit Mages. And even if it was true for the majority of them doesn't mean that it also applies to Lucy herself.

Apart from that Evergreen is a condescending bitch who seems to like putting other people down, so I wouldn't put too much stock in her words.

Also the only times Evergreen saw Lucy fight were during the fight against Flare and in Naval Battle, so even if she had been commenting about Lucy specifically, she could only have based that opinion on hear-say and not anything she was able to witness herself.

Either of the three cases by itself makes her far from a reliable source of information.
