@Marisa22, you've misunderstood the cancellation policy. It has nothing to with a confirmed booking, but comes into play only when a guest wishes to cancel a reservation.
When a guest makes a confirmed booking, there is no 'deposit'. The fee is paid upfront to AirBnb. AirBnB then transfers the amount to you, generally within 24 hours of a guest's arrival if you're using PayPal. It can take a little longer if you use a different payment method.
(In a long-term rental, the first month is paid to the host, and then AirBnB pays the host each consecutive month.)
I strongly advise that you study all of the sections in the link below in order to become familiar with how AirBnB works.
