Cubase Artist 9 and Cubase Pro 9

In my steinberg, label download contain download for Cubase Pro 9 for 10,5 GB.
Before to have Pro version I had installed Artist version 9.0.20 but also I have chaged Microsoft OS from Win7 to Win10Pro than i had dowbload a full version and I had installed them.
My answer is : all 2 version, Artist and PRO, are 10,5 GB, are they the same file?

I believe they are the same program but the license determines what features are available.
