The CORE courses are set out in the best order to learn each stage.
If for example you are not interested in animation, you don’t need to complete all the courses.
However,
It is advisable to understand rigging, animation, etc., etc., because as a modeler you will need to understand the needs of a rigger and animator to supply a model in the condition required for rigging and animating.
Also, you will have a fuller more rounded understanding of Blender if you follow all the CORE courses.
You don’t necessarily need to pursue animation any further if you don’t wish to.
It is totally your choice.
