Each tier card shows a projected profit scenario based on how much the market currently expects the stock to move before expiry. For example: "If AAPL rises to $341 - you could make +$644."
This is not a guarantee. It is an estimate of what your option could be worth if the stock moves by the amount the market is currently pricing in. The actual outcome depends on how the stock performs and when you decide to exit the trade.
The scenarios also show what happens if the stock stays flat or moves against you - always read both before deciding.
