I'm sorry but Kawaki beating the two shinobi capable of fighting people like Madara, Kaguya and Momoshiki on roughly equal terms together is not happening and Boruto doesn't look that old so Naruto and Sasuke haven't turned into old men suddenly plus the Hokage and a man who's travelled the shinobi world may get a little rusty but they could still waste Kawaki's smug ass.

Although, if Kawaki has the same curse mark as Boruto that means he technically 'killed a God' however Boruto did so with assistance and I find it more likely Kawaki is working for this 'God' that gave him the curse mark. But on the off chance he did somehow beat Naruto I still think Naruto managed to survive judging by how non-plussed Boruto is when he talks about sending him where he sent the seventh (if I were Boruto I'd be a little more visibly pissed).
