Points?
If you mean Credits, that is want you have available to spend on equipment or to enter pay tournaments. Your Career Earnings is the total number of credits (play money) you have won or earned along the way. Your Level is how WGT tracks experience and completed rounds...the higher your Level, the more equipment is unlocked in the Pro Shop. Your Scoring Average is roughly the average of your 10 best, out of the last 14 rated rounds...as far as I can tell, that is the main factor in tier promotion.
