We dont know what Sanji learned or how he learned it. It may be that h just knows that Doffy is still a schibukai and that he learned this information from either violeta or an inhabitant beacuse Doffy would definately reasure them that he still is king. In this scenario he would definately warn Law first because they are in more danger due to Doffy actualy meeting them + robin is (or atleast should be ) there with him so he would warn them first. So far the only SH that knows that the Doffy family actualy knows t location of Sunny is Zoro and he is doing his best to warn them.
