No she is talking about Heroes and Villains when she says that.
She says mankind is fond of recounting the exploits of Heroes and Villains then says the we are remnants.
That is why she says forgetting so easily she is indicating humanity doesnt recall that the heroes and villains they are so happy to talk about, which salem is one, are of a forgotten past.
She is directly linking the heroes and Villains as being of a forgotten past. In this case she is indicating herself in that.
That is why she uses WE its not Mankind she is talking about when she uses it but Heroes and Villains being remnants of the past.
That doesnt indicate she is human
It just means she sees herself as either a hero or Villain which Humanity is quite fond of recounting their tales.
And considering Ozpin there is a fair chance that the most common Heroes and Villains of their time is actual her and Ozpin fighting.
So I think you are taking it in a way the writers didnt mean for it to be. Because she is talking about heroes and villains explots being retold but forgetting they are just remnants of a forgotten past.
Keep in mind its not the first time writing indicated something they didnt mean and they later explained it. They had this happen with WOR on Aura which a LOT of people took to mean its always on when they actually meant its not something you need to control when its on.
So it should read like this
"Legends. Stories scattered through time. Mankind has grown quite fond of recounting the exploits of heroes and villains, (Mankind) forgetting so easily that we (Heroes and Villains) are remnants, byproducts, of a forgotten past."
Now to be clear that doesnt mean Salem ISNT human or was once human. Just the line doesnt seem to work in the way you present it as is all.
It may turn out Salem might indeed be human or was once human.
