Selvedge Edge Counting Stitches

When using the s1 method of creating a selvedge edge does it count as the first stitch in every pattern? I’m asking because the dishcloth I’m currently working on has a border of 5 seed stitches and my side borders do not look the same (width-wise) as the 5 rows I first cast on.

Maybe I don’t need a s1 selvedge edge with the seed stitch border.

I would still count the slipped stitch as one of the 5 border stitches.

Thank you. Being a new knitter I always think I am doing it wrong.
