Do I lose when I get a soda from the soda machine at work instead of purchasing it in bulk?
Do I lose if I purchase it in bulk from costco instead of pooling the resources of my friends, starting a company, and buying directly from a distributor?
Is the soda machine a "game of chance"?
The answer to all of these questions is "no". None of them are games of chance.
This would be a game of chance if it was "pay $10 and you might win, but we won't tell you until the end" instead of "pay $10 and if somebody pays $11 we will tell you so that, if you chose to, you can bay $12. This cycle will continue until the item reaches a point that nobody is willing to spend more for the item"
This is not a game of chance because you get to CHOSE if you are going to win, and they TELL you if you will before the conclusion of the auction (or game, in your description).
You ARE simply confused about this, because it isn't possible for a rationally thinking person to make the argument that you are and mean it.
