this would be 1 rep max I would assume. Not many people in the world are capable of any of those lifts for 1 rep, let alone many.

Although with that said 225lb for bench is not that much for a man who lifts but most people likely don't lift. Its probably top 0.01% for women.

Increases in strength usually go hand-in-hand with increases in bodyweight. I did Starting Strength, and gained 10kg in a few weeks. Some of it was fat obviously, but mostly it was muscle. Even though I didn't perceive myself much different everyone else did notice. Also I had to buy new clothes.
