Personally I don't think it makes much sense and is trying to sound fat wiser than it is. That said, if someone is trying to be famous, maybe they are doing things which are unethical or immoral. This may get them lots of fans who love them but maybe lose the respect of friends and peers who then no longer like them. "Love", in this case, not being real love but just the word that gets thrown around by celebrities these days. Just my opinion!

Hard to determine in this specific line as it is likely just philosophy. In this specific context it could mean "Everybody loves you (impersonally) but nobody likes you (personally). However, in a practical sense, both Like and Love should revolve around the same positive concept.
