Cut and pasted from the yum man page:
update If run without any packages, update will update every currently
installed package. If one or more packages are specified, Yum
will only update the listed packages. While updating packages,
yum will ensure that all dependencies are satisfied. If no
package matches the given package name(s), they are assumed to
be a shell glob and any matches are then installed.
upgrade
Can take packages as arguments, upgrade is just like update
except that it includes package obsoletes in its calculations -
this makes it better for distro-version changes, for example:
upgrading from somelinux 8.0 to somelinux 9. *deprecated* - this
command may be removed in the future
install
is used to install the latest version of a package or group of
packages while ensuring that all dependencies are satisfied. If
no package matches the given package name(s), they are assumed
to be a shell glob and any matches are then installed.

No. They are different operations.
