I have a question about paypal

So I wanted to sell my account to this person and they say that I will receive the money in 24 hours is it true you get the money or shouldn't it be instantly receive the money. I always hear that you get the money as soon as they send it and there shouldn't be any wait time. So does it take 24 hours or does it come as soon as they send it?

You should instantly receive the money.
