Would be crazy if it did.
Captain America outgrossed Batman and Superman which is kind of crazy, even with some big Avengers help. GotG 2 is being predicted to eclipse Wonder Woman's opening by a massive amount, which is even more crazy to think about. To have Thor go from being the most middling franchise in the MCU after 2 installments to having hype that appears to rival the hype for a Justice League film, with scale that could rival it as well, it's just nuts to think we are at this point with superhero movies.
If Ragnarok ends up outgrossing Justice League without the Avengers and RDJ, I think that would still be a total shocker. Hell, there is even a possibility that either GotG vol. 2 or Thor Ragnarok could end up beating an MCU Spider-Man. This is the first year of 3 MCU films in one year and I think all of them are big hitters but Thor and GotG are both sequels so all bets are off on how big they can be. Even Thor TDW's WW BO gross was not far off from the Amazing Spider-Man 2, it actually beat it domestically. Just think of how hard Marvel Studios is flexing on fools if Thor or GotG is outgrossing Justice League, Wonder Woman, and Spider-Man. It's still a big "if" but not implausible, which is insane to think it's even a possibility.
