Hello there,
I think you should ask the casino you'd like to play in whether those documents are ok. You can also suggest providing a banking statement where your full address and name would be shown if you can obtain such a statement of course.
Ask the casino and then save the answer in a form of a screenshot, another good hint would be to read the terms and conditions, casinos usually provide a list of the usually demanded documents.
I honestly think that your birth certificate - I guess this is what you mean by the certificate from the registry office - should be ok. But sometimes casinos want an official translation into English, so if you intend to play in a casino that is not under the AAMS (you should not), I'd ask whether the translation would be necessary as well.
I hope it gave you some ideas, let me know what you learn.
