Here's my take on this.

To be a "Professional" whatever, one must meet a series of criteria:

One must have the knowledge, skills and experience above the average person.

One must be able to create a product of such high quality that is above and beyond the average person's ability.

And finally, one must make a living at the trade/craft.

For example:

I can use a saw and cut some wood, but I can't make furniture like a Carpenter can.

I can use a wrench but I can't fix a car like a Mechanic can.

I hope this helps.
