One thing no one can do, here is tell you how good you are. We cannot see you.
But I can offer you something to think about. The ones who win THAT kind of competition are, either professionals, or dancing at a professional level.
You have to ask yourelf, as you are trying to ask us, "What does it take to be a professional dancer?"
The answer is , classes, professsional coaching, conditioning and lots and lots of practice. Pros on stage, for example, don't limit themselves to just one genre of dance. They learn ballet, tap, modern, jazz and many more. Virtually no one learns these types of movements just by watching.
As I write this, I am re reading the question. Perhaps you are asking if we think you should take classes. If so, then, of course, you should! It already seems that you have a passion and what could be better than to pursue a career in something you love.
These lessons cost money, especially as you improve to higher levels. Be prepared, don't expect a job as a dancer for a while. Once you begin attending classes, you will learn of opportunities available to those at your skill levels. Many theme parks put on musical reviews and hire good, but entry level dancers and singers.
Good luck on your pursuits.
