Everyone is a photographer... But not everyone...

A Macau photographer get mad after his 2nd failed of submission to stock photo agency. 

Everyone is a photographer... But not everyone produce photographs that good for commercial usage.

In every professional fields they do have some rules / bar / etc. to justify if you work is up to the standard of the market needed, you can name yourself as a photographer... but you may never be one.

I do suggest him to reselect his photographs and try again.
