Are those free prizes on the website real.Cuz i got an email that said I can win a $1000 gift card. The website is name bigprizegiveaways.com for any who went on that is it true. That u can those prizes or is it a scam?

No you can not win those prizes for free. The "free" prizes websites are shams. All they do is add viruses to your computer, get all your information and can hack into personal stuff, and possibly commit fraud. So my advice to you is that it is a scam and DON’T DO IT!
