Yes, in an ideal scenario, assuming both you and the sender have "verified" PayPal Accounts and neither of you have a repetitive history of disputes, claims or refunds and the sender uses funds from his or her PayPal Account, you would receive the funds almost right away. Additionally, if the sender has both a bank account and credit card linked and confirmed, they would qualify for instant transfers from their bank account meaning you would again receive your funds almost right away. Of cource the sender could choose to use their credit card to fund the transaction and you would receive your funds almost right away.
However, life is not so smooth for all which could cause delays. There some things you simply don't have control of.
