But like, if the pee is already inside me it takes up space and my body displaces water so isn't it the same pee pee level?

You never said you were in the bathtub.

It's that Demitri Martin quote

"There's a small but important difference between peeing in the pool and peeing into the pool"

as someone else ready said you don't lose physical volume when you take a leak, just mass. Since water displacement is a volume thing not a mass thing it would absolutely rise.

you don’t lose physical volume when you take a leak

So what fills the volume in place of the pee?

I don't think anything 'fills' the physical volume internally when you empty your bladder. I think this doesn't affect the volume your body takes up in a tub.

if you had a water balloon in a semi-rigid cylinder that doesn't touch the internal walls of that cylinder, and the balloon is filled with water, and them decided to empty that balloon of water, does that change the volume of the cylinder?
