Why Prophet Married 11 not 4?

Surah an-Nisa 4:3
“And if you fear that you will not deal justly with the orphan girls, then marry those that please you of [other] women, two or three or four. But if you fear that you will not be just, then [marry only] one or those your right hand possesses. That is more suitable that you may not incline [to injustice].”

Surah al-Azhab 33:52
“Not lawful to you, [O Muhammad], are [any additional] women after [this], nor [is it] for you to exchange them for [other] wives, even if their beauty were to please you, except what your right hand possesses. And ever is Allah , over all things, an Observer.”
