You're right. It's probable, but not definite. So you can't just give off the credit of Sasuke's development to Oro, specifically since Oro's contribution (if it exists) was minor and conceptual.
I can when there is manga proof stating that Sasuke went to Orochimaru for training. If Sasuke could do it all on his own he would have shown symptom of it early on.
