I would like to use a picture of the Super Mario model (3D) for my Twitch channel. Of course I'm not a Mario rights holder, but Twitch asks if I have all the rights. Can I still use the picture as a badge for subscribers? (It's a meme on the channel, that's why I chose it)

This https://www.nintendo.co.jp/networkservice_guideline/en/index.html seems to suggest that you can use the picture as a meme. To be on the safe side, I would ask Nintendo.
