hi everyone quick question reworded… all i wanted to know is why do shaders with multiple textures like bumped diffuse only use one draw call and not two?
You’re not clear on what’s going on. Sometimes they need multiple draw calls; sometimes they need one.

A texture, obviously, doesn’t equate to a draw call. You can use as many textures as you have texture units, and draw only once.
