In order to understand what is going on in your camera you need to understand the central idea of exposure. All other learning and advancement is based on this basic concept. Luckily it is pretty easy to take in. Just google for a couple short free video tutorials on the "exposure triangle" and it sinks in pretty quickly.
You want a proper exposure meaning not too much or too little light on the sensor. There are 3 variables you (or the camera) can manipulate to control the amount of light hitting the sensor: time (shutter speed), opening size in the lens (aperture aka f/stop) and sensor sensitivity (ISO). Three things interacting like this just begs for someone to come up with an explanation involving a triangle, and that's all the exposure triangle is. Watch a couple of 2 to 5 minute tutorials and you'll be glad you did. All those settings on the dial will make sense (Tv, Av, Manual).
