The level of knowledge or skill isn't what determines who a professional is and who isn't. The difference lies in who gets paid to do this and who has to pay to play.
Almost none of us get paid to shoot and even the few who have legitimate sponsorships can't make a living out of shooting alone. So whether you agree or not, hardly anyone in this game is a professional. And those who are make it by teaching others or some other industry-related job.
The difference between most of us here and most shooters in the country is that we decided that we were going to become as good as our finances and time allows and we were going to delve into the art and science of long range shooting to master as much of it as we can.
The difference between those who you think are pros and the rest is that we decided that we were going to learn how to do this shit well and not sit on excuses.
Almost all of us started as you have. How far you go is entirely up to you.
