Popular gurus get millions of views on their videos. Lars Christensen and Tyler Beck are popular contributors. Each of them has plenty of videos to teach you everything you need to know to get started designing for your ceramic production. If you get stuck, there are hundreds of places on line to go to find help. It is helpful if you know how to do a screen recording (e.g. using Screencast-o-Matic) to be able to demonstrate your problem. Getting specific answers to specific problems is a surefire way to progress in your knowledge. The first item to learn is sketching, if you can master that much of what you did will be modifying sketches (e.g. extruding, revolving, sweeping and lofting them).
Intimidation by the complexity of this type of software is the biggest obstacle you will face to learning 3D design (for 3D-printing). That being said, the new mission of AutoDesk, the leader in CAD software for 30 years, is to make it easy and universal! Fusion 360 has a lot of advantages. It is a standard. There is a simple learning curve via Tinkercad.com, videos on Youtube, easy online help and many freelancers to hire (at Upwork.com). It is free to qualifying users (teachers, students or people who earn less that $100k/yr), the fact that software of this kind of power and utility is actually available to anyone that wants to try it is amazing. Fusion 360 (and other 3D design products) cannot run 3D printers (3D slicers do that). Fusion 360 is very demanding on the processor and graphics hardware of your computer, typical laptops are not powerful enough.
3D Design software has revolutionized traditional ceramic manufacturing, now it is accessible to hobbyists and potters.
Standard 3D printing technology (not printing with clay itself) is very useful to potters and ceramic industry in making objects that assist and enable production.
