I believe that only a few or none of the universes will get erased at the end of the ToP, or many will get erased and then restored either via Zeno or the Super Dragon Balls. If a character gets erased once they fall off the stage as some people are suggesting then that changes things a bit. The ones with the least speed, power, and mobility will be knocked off quickly.
I think Zeno will be convinced to not erase any universes, and instead start hosting tournaments regularly, because of how much excitement the ToP will give him. Look at how much excitement he's gotten over Majin Buu, Trio De Dangers, and Goku vs Toppo.
If Zenos does stick to his rule of erasing universes, I believe whoever has the Super Dragon Balls will restore 1 or all of the erased universes (Probably Universe 7, but could be 11 who knows)

We don't really know how powerful the Super Dragon Balls are, and Zenos abilities are extremely vague beyond just erasing things at will. He is not completely omnipotent though, because he was able to be copied just by manipulating time. I'm sure he could 'undo' it if he wanted to, but if Zeno can be affected by time travel, then it shows he is not completely invulnerable to everything.
Also since the Kais/Gods had such strict limits on time travel with the rings, it makes you wonder if this might be the one weakness that even Zeno has.
