I don't remember FGO saying that Clairvoyance was part of the requirements, IINM Merlin was simply saying that the 3 that we know qualify for Grand Caster all have a powerful Clairvoyance that lets them see into the future or past of their era or beyond. And tthat's not just any rank of Clairvoyance, since a lot of non-Casters have a more basic Clairvoyance and that's defintely not enough even if they also qualify for the Caster class.
