No.  A server entry will setup a single NTP server.  A pool entry can
setup several.  You can experiment by configuring a single pool and then
looking at how may peers are reported by ntpq -c peers.  I don't know
the details of how it works, but I'm guessing "server" looks up IPs for
hostname and uses only one of those (like typical uses of hostname),
while "pool" looks up IPs and uses all of them.
