Inside I found configuration files for Deluge, which I needed to for a list of torrents. Does it contains all similar files?
If that so, can I just copy whole folder before reinstalling whole Ubuntu and then paste it back, preserving settings for programs?
Thank you.

In your home folder (~ , usually /home/<username>) the .config folder has lots of config files for many programs (some use other "hidden dotfiles" that begin with a dot, like .xxxx folders or files, also in the home folder) and often the desktop / display manager settings too.
If you wanted to back up your whole home folder that would be a good idea too, and could later restore (copy/paste) it to retrieve it's saved settings. If you change user/usernames, then the owner of the files should match the current user.
