How do you expect to be able to draw the animation, The Screen, Scroll, Create menus, create controls after you learn how to make your sprite animated? And you can skip around the tutorials. If you don't understand how something works read the commented code that is all over the place on that site.
I barely know SDL and by reading the site I can tell what each line of code does just by the little comments lazyfoo placed. I am able to skip around the tutorial.
Learn how to create a blank screen first. Then you'll be able to learn how to load an image. Then learn to move it. Once you can move it learn to animate it. Skipping around tutorials has steps too.
