I want to learn photography and open my own shop in the future, but I have no art foundation. Can I learn?

As long as you are willing to learn, there is nothing you can't learn. First of all, sketch is also the basis of modeling, so it usually starts with sketch, and then it is the basis of color. If I want to learn photography, it is necessary to learn color, which is helpful to your composition, color and light treatment. This is a very important basic course.
