Is there a way to Acces DataStore Universe wise? (I really would love an answer)

Is there way to get GlobalDataStore on a different server but same universe,I heard you can do it on wiki and I've tried but only received an error.If you know the way just post an example and a small explanation.

Wondering how to access DATASTORE universe, wise like let's you say save a players name on one server and access on a different server(same universe)

I'm not sure I follow your confusion. The data stored in a Game's (as opposed to a Place's) DataStores will be accessible to every Place within that Game automatically, given a few seconds for the caches to update.

This answers your question, but if you edit your question to include your buggy code, I'll happily edit my answer to try and fix that for you.
