RS

I appologize for asking likely obvious and ridiculous questions but I am BRAND NEW to knitting. Knitting my very first item and am teaching myself with no one to ask...
I am knitting from my very first pattern. It is a pattern for sock monkeys and other animals made by Patons. I'm making the elephant and so far the entire pattern has been in the round. The pattern has just switched to knitting with only 2 needles and says "Work back and forth across needle in rows". I'm assuming this means normal knitting, row by row. Is that corect?
The 1st row says (RS) Knit.
I know that (RS) means Right Side, but is that indicating that the side I start on WILL BE the Right Side, or is there already a right and wrong side after casting on and I should be knitting from a specific side?

Thank you so much for your time!
