Yes, but after the program is started you can do anything. AFAIK the important part of the distinction is the behavior when starting the program - if you start a GUI program from the console (Ex. calc), cmd doesn't wait for it to exit. And if you start a console program from Explorer, a cmd window will pop-up (you can hide it, but it will still flicker briefly).
