That’s not how I see it. Here’s how I interpret it.

Johnny practices his whole life to be the best he can. The devil shows up and challenges him, so he says it might be a mistake (probably knows the devil will cheat), but trusts his training and accepts. He plays his heart out and beats the devil at his own game, despite the devil trying to cheat. He wins the golden fiddle and, filled with confidence, says he’s up for another challenge. He knows he’s the best because he beat the cheating devil.

I don’t see it as talking about pride or gambling, but knowing your abilities and reaping the fruits of your labor. If it was about pride, he would’ve been caught by the devil.

Gonna have to agree with the one replying to ya here - you did not explain what you meant at all.

If you keep asking the same questions past this point, I’m going to assume you’re just trolling me.

Goodness gracious. I literally just didn’t understand your point. 🙄
