I was able to get this with the player. I bet the minimum bet of 1,000 but I don't think it matters.
Baccarat rules are as follows:
If neither the player nor the banker is dealt a total of 8 or 9 in the first two cards (known as a "natural"), the tableau is consulted, first for the player's rules, then the banker's.
Player's ruleIf the player has an initial total of 0–5, they draw a third card. If the player has an initial total of 6 or 7, they stand.
Banker's ruleIf the player stood pat (i.e., has only two cards), the banker regards only their own hand and acts according to the same rule as the player, that is the banker draws a third card with hands 0–5 and stands with 6 or 7.
If the player drew a third card, the banker acts according to the following more complex rules:
If the banker total is 2 or less, then the banker draws a card, regardless of what the player's third card is.
If the banker total is 3, then the banker draws a third card unless the player's third card was an 8.
If the banker total is 4, then the banker draws a third card if the player's third card was 2, 3, 4, 5, 6, 7.
If the banker total is 5, then the banker draws a third card if the player's third card was 4, 5, 6, or 7.
If the banker total is 6, then the banker draws a third card if the player's third card was a 6 or 7.
If the banker total is 7, then the banker stands.
Therefore the ideal thing is to get as many face cards or 10's as possible since they are worth 0. As you can see in the video I win with 7-4-10 betting on the player. You just add up the values (for double numbers its only the last number. so 7+4+10 = 21 and the last number is 1 so the overall score is 1.
The banker got 10-2-8 which adds to 20 and their score is 0 since 0 is the second number in 20.
Just stick to either the player or banker and it will unlock eventually. It took me about an hour maybe, but again its pure luck if its going to come out.
