It's harder for a public figure to win a libel suit than it is for a private individual, because the legal requirements are different. But even a famous person has only to prove that the newspaper published a false story that harmed his or her reputation and knew or should have known the story was false. (Melania Trump would have no chance suing People because the offending passage, true or not, wasn't damaging.) Such lawsuits rarely get filed — and even more rarely succeed — because news organizations hardly ever do what the defamation laws punish.
