To some degree you're right, reading doesn't make you intelligent in and of itself, but I do think constantly reading like that does make you to some degree smarter. Like even if you're reading slop, you're probably smarter than if you had been reading nothing.
It has also been proven that reading makes you more empathetic, because you are actively putting yourself in the character's headspace.
