Translation:The girl is smart.
Whenever I've asked my wife (Korean) or any of my Korean coteachers, each of them has said that 똑똑하다 and 영리하다 mean the same thing in Korean.
Also from naver dictionary:
[똑똑하다 ; Adjective ... 2. clever; bright; sensible
머리가 좋고 영리하다. (Intelligent and wise.)]
[영리하다; Adjective clever; bright; intelligent
눈치가 빠르고 똑똑하다. (Quick-witted and smart.)]
