In the second season there numerous Digidestined all over the world, the main ones on the show didn't know about them until they needed them for the final fight (memory is sketchy on that).

Tyler already said that she's not one of the original Digidestined, so that is fine.

My memory is a little hazy as well but I'm fairly sure that the other people with Digimon in the second season were only tamers and not Digidestined, which are not the same thing; Digidestined are the chosen ones essentially, fabled warriors, while tamers are just people with Digimon.
