Do I need to be very comfortable with groovy to master gradle?

I am working on a software engineering team as part of my internship. I am learning about all of these technologies used within our stack. My only experience with gradle before this was within Android Studio and I did not get down to the nuts and bolts of it.

I have taken a brief gradle Udemy course since beginning my internship and after finding out that it uses groovy as its DSL, I want to know from power gradle users; To master gradle should I get really comfortable with groovy.?
