This is very possible but I suggest earning as many free credits as possible through videos, surveys, or even when you are shopping... consider using one of the sponsor offers to buy a gift and earn credits at the same time.
You can earn credits through playing by playing free tournaments (not a lot of credits), credit tournaments, match play challenge, blitz challenge, and Country Club tournaments...
The players have gotten better and better at this game so the scores are very low.... practice practice practice!
