It isn't really that hard. It's daunting at first but there are so many tools out there that make them very easy to use. For what you want, you'll need blender and unity at minimum. Everything with blender can be done with cats plugin in a couple of clicks. Everything in unity can be done by dragging and dropping into slots.
All of us started where you are now by the way. We're all amateurs bar maybe three who do 3d modelling professionally.
