Ki doesn't come from everything. Ki comes from every living thing. It's literally translated as "life energy".

Moreover, your classification of "alive" and "(un)dead" is a bit wonky. If, say, a rotting corpse still had a soul, then by your definition that rotting corpse would be "alive", despite being a corpse.
