Do you have a free month when you pay with a Netflix gift card?

So I wanted to create a Netflix account for myself, only my parents don't want me to do that. That's why I thought about giving myself Netflix gift cards.

Now I have the question: If I create a new Netflix account do I have another trial month that I don't have to pay or will the money be used immediately on a gift card?

You can also try Neflix for 1 month for free without a gift card or such a rubbish

First you create an account and with a new account you have an immediate free month and you only pay when the month is up
