I want to learn photography. Can it be a career? I like photography.

Whether you can become a career is not whether you like it or not.

I like singing, but singing is out of tune (but I still like singing), so no matter how much I like it now, I can't take singing as a career.

Photography is the same.

You can't just do what you like.

It depends on whether you have this ability. You need a chance.
