No, wafb is right. Whenever you win a bet, you always get back what you bet PLUS your earnings. Therefore, if you bet 5,510 and win, you get back what you bet (the 5,510) plus 5,510 (one times what you bet).
A 2/1 means that you get 5,510 plus 11,020 (or twice what you bet). If 1/1 means that you get back what you bet, there would be no point in betting.
