Yeap, As the technology evolves the entry barrier lowers and the minimum quality standard rises. Good you still want to continue making games despite some bump in the roads. It is like Cosmic Trinity Games said. Game development (like any kind of programming in the end) is a lot about solving problems. Just don't pressure yourself in making things big, start low, even with ugly prototypes not made for publishing. (Like a simple platformer, clicker, or coin picker game). If you still wanna try using AI to create visual art perhaps Krita with the plugin 'Krita AI diffusion' may help you. Or things like you can found in pinokio, like RMBG-2-Studio (it's a background removal tool i like) or FaceFusion (face editing program) using the face-edit mode. You can run many of these in a average low end gaming pc.
