No, that is not entirely correct. As I said before, "back" refers to placing a bet on a particular outcome to happen, while "lay" refers to offering odds on a particular outcome not happening.
Team A Lay- 1.04
I don't know anything about the draw outcome though. I haven't tried it yet since I had no idea. I'm not going to place bets on this market either lol.
Yes, if you "back" Team A, it means that you are betting on Team A to win the match. If Team A wins, your bet will be successful and you will receive a payout based on the odds of your bet. However, if the match ends in a draw or Team B wins, your bet will be unsuccessful and you will lose your stake.
On the other hand, if you "lay" Team A, you are essentially betting against them. This means that you are betting on the other outcome(s) to happen, such as Team B winning the match or the match ending in a draw, depending on the specific terms of the lay bet.
