I am also kinda agree with you because Pakistan also gave good performance in the series they are not only depending on luck. But unfortunately Pakistan has the weakness of Batmens because I saw they are constantly depending on babar azam and rizwan for batting and when they can't perform well Pakistan lost that match. I they should immediately change the batting lineup Otherwise this will happen again and again with them.
Pakistan have big dependence over Babar Azam and Mohammad Rizwan. However the bowling strength keeps them at good position. Even after scoring 137 runs they gave good fightback and took the match till the 19th over. Compared to the initial matches now there is performance coming from Masood which is really good for Pakistan. As suggested, opening change or someone needs to be prepared for the position when this combination isn't able to give success.
One thing is to note that when Pakistan top order does well, everyone including the middle order does well. Top order failure means loss for Pakistan. Pakistan have come in this position only because of their good bowling performance otherwise their top order dependent team would have been far down. But if they make changes in this batting site, it can be good for the team. After Babar Azam and Rizwan if the Pakistan Cricket board select two others good batsman or reorganize then i expect Pakistan cricket can be one of the strongest and reliable cricket team in the world.
