Apart from that, Sanji has been taught by Ivankov up to 2 years as well and unlike Bellamy, who was yet part of Doflamingo's family IIRC, Ivankov actually taught him something.
Heck, even if Ivankov didn't train him directly, there were enough opponents in which Sanji could have learned koka.
Obviously good enough in which Sanji developed good CoO.
