Yes, thats sufficient normaly.

What you saw where these. 
apt update  - update the package list and versions in cache localy.
apt upgrade - upgrade packages. (optional --autoremove --purge) 

--autoremove remove unused packages (related to other packages you removed) 
--purge cleanup any leftover files

And the option. 
apt dist-upgrade
If a packages needs an extra package that isnt installed yet, it stalls, 
This might prevent you from breaking the system or it did break it. 

Then dist-upgrade is the option. 
( prefered with  --autoremove --purge ) 

I hope that explains abit.
