I think about it this way: Without the very specific interaction of the Vanishing Rasengan, Boruto would've been useless, and without Sasuke's powers and efforts, he couldn't possibly have blinded Momoshiki. Without Naruto's extreme levels of power, boruto couldn't have blown him to bits with that Rasengan. A rasengan that hurt Boruto's arm, a feature only previously seen in the Rasenshuriken, implying it was not a regular rasengan.

Even so, they were at a massive disadvantage because Momoshiki attacked so close to home, meaning Naruto and Sasuke were forced to tank lots of unnecessary abilities. After that, Sasuke had to travel between dimensions and Naruto had quite a bit of chakra extracted, putting them at a disadvantage.

And if it weren't for Katasuke, they would've won anyway despite these challenges, since they already had won at that point. Circumstance gave Momo a second wind and circumstance gave Boruto the ability to defeat Momoshiki.
