Probably yes.

<man apt-get>

            upgrade is used to install the newest versions of all packages
            currently installed on the system from the sources enumerated in
            /etc/apt/sources.list. Packages currently installed with new
            versions available are retrieved and upgraded; under no
            circumstances are currently installed packages removed, or 
            not already installed retrieved and installed. New versions of
            currently installed packages that cannot be upgraded without
            changing the install status of another package will be left at
            their current version. An update must be performed first so that
            apt-get knows that new versions of packages are available.

            dist-upgrade in addition to performing the function of upgrade,
            also intelligently handles changing dependencies with new 
            of packages; apt-get has a "smart" conflict resolution 
system, and
            it will attempt to upgrade the most important packages at the
            expense of less important ones if necessary. So, dist-upgrade
            command may remove some packages. The /etc/apt/sources.list file
            contains a list of locations from which to retrieve desired 
            files. See also apt_preferences(5) for a mechanism for 
            the general settings for individual packages.
