Why is my older brother 5 inches taller than me

[J_Lacks_PSL]

Please skip if you DNR, also I’m not complaining about my height, just trying to make an inquiry.
I went to my doctor, and my projected height is 5’11/180 cm (I’m 16 and currently 5’10/177 cm), assuming I don’t hit a significant growth spurt before finishing puberty. But my older brother was far more developed and in fact was already 6’3/190 cm at 16 (he still has this same height after 3 years at 19). Also in every single way (yes, ___ size, bodily hair etc.), I’m far less developed than him. In terms or height and growth related observations in general, simply looking at frame, my torso appears much more squished and disproportional than his, especially because my arms look too long for the rest of my upper body, while his build generally looks much more polished and proportional, despite me not actually being wider than him in any way.

Am I just a really late bloomer while he was really early, or is there a chance that I’m just going to end up far less developed in every way than him?
How likely is it, that I end up significantly taller than the projected 5’11?

Also no, I don’t have any medical/hormonal issues that would make me abnormally underdeveloped in terms of puberty.

Thanks for reading, have a great day

My brother is 5'11 while im 6'5, its purely genetic, 5'11 isn't bad and you can easily fraud to 6'1

height genetics are pretty complicated and it’s not as simple as oh he’s tall so i will be too, it’s polygenic so it’s a combination of a bunch of different genes that influence final height, seeing as tho sex cells undergo meiosis and then genetic crossover it’s likely that his recombinant dna just happened to have a tall gene that literally wasn’t in the dna ur sperm and egg cells had and his coded for a taller final height than urs. hope that makes a little bit of sense
