That’s one of the things when we’re starting to learn that seems frustrating, you can’t get your things to look like what you see the teacher doing in the video. But that is not necessary, so much stuff influences how each Blender looks, it basically doesn’t matter. You can have a different HDRI set up, the rotation of the HDRI, the Blender version changes the shading, etc, etc. You will get different results most of the time, and that is a good thing, you don’t ant to just copy paste what you see.
