This is a link that shows the only way to unlock each character. You will have to do 150cc and above and time trials to unlock some of them. You will also have to earn a star rank in all cups.
If you want to get better practice. Use bikes not karts. When in a straight road use wheelies. Hold a banana or shell for defense. Use baby luigi and the magikruser, baby daisy and the bullet bike, yoshi and the mach bike. In time trials use fast bikes. Use the 3 mushrooms at the right place.
