Incorrect. The Rambam specifically says that ANY hashgochoh pratis we receive is directly correlated to our madreigah.
I am sure you are not the first person to notice the Gemorah in Chullin 7b; if you feel it contradicts the Rishonim I would encourage you to research any relevant sources that deal with it and report back. I should point out that not every Aggadatah gemorah is considered definitive by the Rishonim. Perhaps that is a place to start. Hatzlochoh.
