If an example of where there is a difference would help, consider these two possibilities:
1% of the population takes over the universe;
everyone is obliterated (99% chance) - or “everyone” takes over the universe (1% chance);
To an egoist those two possibilities look about equally bad.
To those whose main concern is existential risk, the second option looks a lot worse.
I would call myself more of an egoist, and I would say the first possibility looks really good and the second possibility looks pretty bad. I of course assume that I am part of the 1%.
