What needs to be done to properly use installed programs in ubuntu?

Question

ubuntu

Everything seems to fall into place a little, the only thing I did not understand was what to do with the installed programs. For example, I put atom

sudo add-apt-repository ppa:webupd8team/atom
sudo apt-get update
sudo apt-get install atom

The next thought is that I will work with it in my user locale and therefore I do not need to run it as a super user. Therefore, you need to run it without specifying sudo. This is true?
If yes, what can be done to avoid this problem?
