I think you're reading too much into that. I took it to mean what it literally said - that she was the strongest demon in the show that never held the title of "Ruler of Hell." Which actually lends itself to theory of Azazel being strongest and Lilith being second - but since she never ruled hell and Azazel did, she comes out on top in that category.
