By the time it opened it was also a foregone conclusion that it would do at least 2/3 of what it's currently doing. Before Get Out opened I don't think anyone rationally predicted it'd do even half of what it did. Get Out is also a much riskier movie in every way. IT is horror, sure, but it was basically sold as a flashy blockbuster ride kind of horror, and it is one as a movie. (Which is also part of why I disagree with the "ultimate horror movie" etc. notion. It's a big populist hit that's come out at exactly the right time, that by itself is not gonna make it another Exorcist or Sixth Sense.) I get where you're coming from but I'd still place it at #2.
By that logic Despicable Me 3's domestic run is a greater story than Get Out and Hidden Figures. In other words: no.
