Is it true, that only 2 % of the world will go to heaven?

I personally dont believe this, because the way i see it, if you accept jesus christ in your heart and repent for your sins, you will be saved. But according to harold campings predictions, only 2 percent will be saved and the other 98 percent will go to hell for eternity. I was just wondering whats your alls thoughts are? Serious answers only please
