A market maker sets a bid (the price at which they buy) and an offer (the price at which they sell).
The offer will always be higher than the bid, and they make the spread between the bid and offer price.
If buy and sell orders are roughly balanced, they will not lose money. The idea behind purchasing flow such as Robinhood's is that the traders are random noise traders, with a balance of buys and sells as such.
So that MM will in fact buy orders that may on the face of it be a loss.
