I've never cared for this trope - the idea of "fate" and "destiny" always feel wrong. It can be done well - see Star Wars wherein Anakin is the chosen one, but it isn't necessarily *good*. That said, I don't think I would use it in a tabletop game. If a player wanted to be "chosen" for something, I'd probably tell them about a prophecy and give them the opportunity to fulfill it, but I wouldn't force it at all. And I would limit the scope so the other players have similarly important tasks if desired.
