You will find this type of issue a lot with Blender, it just changes too fast, there is no way to keep up with it. If you are using the latest version, in the beginning nothing will match with the content that is out there. That is why it is always recommended to use the Blender version the tutorial was recorded with. The overall knowledge is more important than the where did they put this button. So I 100% suggest you do a course with its respective version of Blender.
