To became a good photographer you do not needs expensive caamera you have positive thinking and smile in your face . Every enviroment you will see good but one of them will be very good so you will find that very good images if you have positive mind.
To become a good photographer you have to know how how light works and how your camera captures light.
The good photographers that I know understand optics and physics and make the appropriate investment in lenses, tripods and lighting equipment to capture the image.
I agree that a person who just goes out and buys expensive equipment is unlikely to become a great photographer. But great photographers understand their equipment and are always seeking improvements.
