Well he said it so who knows. Maybe we as the Wol being Azem were special and he may have hoped that we would join them again. But he says that the rest of the source will be sacrificied and when everyone looked angry he was all like "are you angry that you will be offered to Zodiark?". So yes for me that means that he included all the people that would have survived.

And about the second sacrifice. The races that seemingly exist on the first and the source (and the 13 shard too seeing those survivors) must have existed before the sundering to be on all those split planets. For me it makes the most sense that they existed either as new races when Zodiark brought life back or they were created as kind of familiars by the Ancient.
