then why there is non-zero balance on both of these addresses?
I'm sorry, I'm new to this topic, I'm just trying to figure out what's going on here and most importantly HOW...

because from the moment they convert the BTC into EUR, their identity is revealed and they are no longer anonymous. If things go wrong, the “lucky winner” then has a problem on their hands when they are forced to account for their actions or make a statement. Thanks to KYC
