Wonderful, welcome!
If you're anything like other people, your experiences might really vary: you might instantly catch on to how things go and have a great time in some places, and struggle and feel confused in other places.
In this modern age, there are some good examples of other people playing the game online (both written reports and videos of people playing). They're not always exciting to read/watch, but you might find looking through one or two very useful (they illustrate much better than a rule book how things are supposed to go). If you wanted to try playing a little bit with someone online (over Skype or Hangouts or similar), I'm sure someone would be happy to do that, too - at least to answer some of your questions or demonstrate some part of the game.
Keep in mind everyone plays a little differently, and many parts of play are a personal, stylistic choice: how much detail you use to narrate things, how strict you are about calling for moves to be rolled, and so on. Feel free to explore and try different things! It's good to find what you don't like as well as what you DO like.
