Yeah, Pakistan really benefited from South Africa's defeat against the Netherlands. Each of the other teams has done well to reach the semi-finals. The Pakistani team was lucky enough to reach the semi-finals but gradually improved as the tournament progressed. Due to their middle order weakness, everything was shattered.
Actually their middle order and lower order was performing well in the initial phases. Back then the main issue was that both the openers (Mohammad Rizwan and Babar Azam) were scoring too few runs, and that too at a very slow pace. And then the injury to Shaheen Shah Afridi removed the venom from their pace attack. On top of that, the spinners were struggling in Australian pitches. And then Babar regained his form when it mattered the most. But the team balance was not there. One or the other component was always performing poorly. England on the other hand had good team balance.
). Coming in to the tournament, they had perhaps the best batsmen and bowler in T20 cricket (Babar Azam and Shaheen Shah Afridi). But then, they couldn't keep up with the expectations. The good thing was that Babar regained his form when it mattered the most. But in the end, England proved to be a much better team (even without Mark Wood). 
They held their emotions in this big match and were well rewarded.
