Hi @Cailynpaige96,
Welcome to the Community!
With PayPal, you receive money when someone sends a payment to your email address or mobile number. Once that happens, we’ll send you a message letting you know you have money available. We do sometimes place the money from a payment to one side, in a pending balance; however, it's important to never ship an item until the payment shows as "Completed" in your PayPal account. You can read further information on common scams here.
I hope this helps you out,
Craig
