Only one observer is immortal in one world, you can’y meet others.
It is the same like in lottery with one prize. If you win, other has lost.
But Anthropic principle metaphor is more correct. You don’t meet other immortals, the same way as Fermi paradox work and we don’t meet other habitable planets. Because winning is so improbable that we could find ourselves on habitable planet only because observation selection.
