The weight limit is likely more a pressure and CoG loading thing than anything else - the entire floor covered with people experiences a lower pressure than the load distributed through the abrahms tracks but the CofG may stay the same as with the tank or may shift around a little.
In terms of overloading, you just need to fly a little bit faster (to double lift you only have to fly 1.4 times faster everything else being equal)
C17 max payload appears to be 170,000 pounds, even with 823 on board at 200Lbs each that’s 164,600, well beneath its limit and I doubt the average weight was that high
