This is a subject that comes up frequently in photography. I think this is because many novice photographers think they need a fancy camera to take good pictures.

Gear, particularly the lenses you use, matters depending on your preferred genre of photography. Beyond that, the difference between and low and high end cameras tends to be build quality and the ease of use.

It's important to remember that these are just tools. I've learned that everyone shoots differently, so it's important to find the right tools that work best for you.
