No risotto and orzo are not the same thing and are different.
The Orzo and Risotto seem similar but the Orzo is a grain-shaped type of pasta while the Risotto is a creamy, decadent Italian dish made from rice and broth.
The Orzo can be used as a substitute for Arborio rice in making Risotto but they are not the same thing.
The taste between risotto and orzo are also different at least to me.
So if you want to make risotto or orzo you should use the correct ingredients or if you want risotto or orzo they will be different from each other.
They both are good but they are different.
