The correct form is `apt-get dist-upgrade` but that's just the command to update all packages to the latest versions in the same release of the OS. It is the equivalent of `apt full-upgrade` if you have the more modern `apt` command rather than `apt-get`.
So, no, that will not upgrade your distro.
The recommended course of action for Debian is to edit the repository config files, change to the new release names, and then do a full update.
That is still wrong.

It's a big job.

Ubuntu wraps this in simpler tools: `do-release-upgrade` from the shell, or Software Updater for GUI users.
I just upgraded my Ubuntu 24.04 box to 26.04, and my OpenBSD 7.9 box to 8.0. OpenBSD is quicker and easier.
