No!!!! Thats not what Stan Lee ever said. Stan created Thor as a god to be the only character in marvel who's overall power could match Hulks strength. Thor was never meant to be stronger than the strongest one there is. I keep hearing people use Stan Lee's words as proof and then they twist them to fit their belief. On top of the fact that Stan lee created these characters how many years ago 50. Overtime alot of things have changed one of them being Hulk,who has gotten stronger and stronger over the years and is now without a doubt Thor's superior in physical strength.
