You see landscaping in there?
Most of the rest of those professions require master's degrees...
All except maybe nurses and military officers, and maybe there exist a few more but they all require college as well..
Are you really quoting a source as unreliable as Wikipedia? And thats a pretty short list of professions. I dare say there are a number of professionals who would take umbrage at not being included in that list.
Look at the actual definition of professional and you will find that, while landscaping is an industry, referring to yourself as a professional of an industry is a perfectly proper use of English.
