One of the best resources you can check for Unity related help and for seeking clarity and answers from is the official Unity documentation and manual.
https://docs.unity3d.com/Manual/index.html
This documentation section can be difficult to read especially if you are new to Unity, however, information will make more and more sense as you develop your skills. Typically once the fundamentals are known, reading the documentation can become easier over time to digest and can become more of a valuable resource.
