as of now, Chatgpt can generate trivial pieces of code, but you'll need to debug them extensively, extend them, and most importantly stitch them together to make them work as expected.
Also, If you're aiming for a high paying job, I'd suggest you to start with competitive programming and DSA as that will help you develop problem solving skills and the right intuition required for understanding how things work.
Also, almost all of the big tech interviews have extremely high weightage for DSA based problems. Starting early will help you prepare better.
