If you have less growth hormone does it mean you have smaller bones compared to a person the same height and weight at 6'1 male?

Growth hormone: If you have growth hormone deficiency during childhood, you will have short stature (you will not be 6'1"). Probably some decrease in bone mass too. There is a wide range of "normal" GH, and it fluctuates a lot throughout the day, so "less growth hormone" does not mean much. Unless suspicion of a disease, I don't know why you would even measure GH in a 20 yo 6'1" male.
