Which tutorials are you using? Since you're new, I'm going to go ahead and direct you to the
"Help! I'm new!" FAQ. That will help explain things to you and get you going in the right direction. As for getting paid, yep, it's a reality. Make your game for the XBox 360 and you can release it on XBox Live Community Games (not to be confused with XBox Live Arcade). When you release your game, you can set the points your game costs and as people buy it, you get paid. Check out the
FAQ on XBLCG for more information on that.
Finally, if you're really hunting for a great complete game walkthrough, I highly recommend Nick Gravelyn's Alien Aggressor tutorial. It takes you from start to finish on making a Space Invaders clone. Great starter for beginners.
Welcome to the forums and best of luck as you learn to make games!
