I’d recommend starting with this overview on how responsive images work.
Next, we have a guide on how you can serve responsive images with Images.
Note: The examples in this guide use the URL structure for transformation images that are stored outside of the Images product, e.g. /cdn-cgi/image/fit=contain,width=320/assets/hero.jpg 320w. Since you are storing with Images, make sure that you use the correct imagedelivery URL structure like you have in your example. You can either create a predefined variant or use the flexible variant URL structure.
