Confused 'newbie' understanding st st in pattern

I am going to be starting a stuffy bunny for a friend’s baby but before i start im am already confused >_<

pattern says

k2together, k3 9 times (i got this)

st st 3 rows (i dont got this)

k2tog 3 times, k3, k2tog 3 times (got this)

does the st st 3 rows mean ‘purl 1 row knit 1 row purl 1 row’ then continue on with the k2tog row?

Welcome to KH. Yes, st st = stockinette stitch so in this case you’ll purl a row, knit a row, purl a row as you say.
