Help me start with AI photo editing

Hi, I'm a professional photo editor and I've come to the understanding that I need to learn AI tools for my business. I'm completely new to this and I've been reading a lot of stuff this last 3 days but it made me so confused that I'm not sure what to do. One thing I understand is that the best for me would be to use ComfyUi + Stable diffusion. I've already downloaded ComfyUI but once I opened it I could understand nothing, I got stuck in an endless list of I don't know what. As you read I'm literally at step 0, and I'm looking for any online resources that could help me understand better.
