BS vs Graduate degree

I'm currently graduating from community college and am in the process of transferring to a 4 year school to get my bachelors, but they said this when I was asking questions about my major.

Your major is listed as Childhood Ed. You can get your BS in it but we do not have a graduate degree in Childhood Ed. You can get a graduate degree in Special Ed or Literacy if you would like, which we do have. You still have plenty of time to figure that out.

Does anyone know what it would mean if I can't get a Graduate degree but I can get a BS? Because I will need my masters bc teachers need to be in New york state but I dont need to right away, I don't necessarily need it from this school, and im not 100% sure if thats what a graduate degree is.

Sorry if this is a stupid question, college terms confuse me and the only other people I can probubly ask is my parents and they would probubly make fun of me for not knowing (also BS means a bachlors degree right?)
