Is she your relative or your sister?
In any event: so let her learn. I certainly have no problem if she wants to learn privately. But becoming a (conservative) rabbi is quite different than just learning privately.
People don’t become rabbis because they are “very smart and academic.” Some become rabbis because they want to serve klal yisroel. Some become “rabbis” because they want to destroy klal yisroel. Some become maharats because they want to push a social agenda on klal yisroel which is against the Torah.
So that’s the relevant question. Not why she likes learning.
