People say "put it in a PDS member." Is a PDS like a folder? And a sequential file is just one long file?

Pretty much. PDS (or PDSE) = library with members. Sequential (PS) = one dataset, no members.
Source code usually lives in PDS members. Big data files are often sequential or VSAM.
PDSE is the newer flavor. Same idea for most beginner work.
