Question about what I can and can't do in youtube content

[Jeeqbit]

Well for starters, they rarely punish your game account for actions outside of the game.

However, in very rare cases, they have punished content creators' game accounts, often using the Materials Usage License as a reason. They cannot do this if they don't know what your account is. It's your decision to connect your accounts by linking to your YouTube via your game or forum account, it's your decision to use footage showing evidence you control a certain account and it's your decision to declare in videos or elsewhere the connection between your YouTube and game accounts.

It is actually far more likely that YouTube would punish your YouTube account for that line though.
