Yes. Downloads are always instantly made available if the customer pays with a payment method which actually collects payment immediately, such as a credit card or PayPal, etc.
If the customer pays via check/moneyorder then the storeowner must go into the ORDER via the Admin and update the Order's status from Pending to Processing, which will automatically release the downloads. Of course, you should never do that until the check/moneyorder has been received and has cleared the bank.
