What your describing could be Bufferbloat. Google this and run a test (Waveform). 

If you get a poor result one way around fixing this and improving the connection and latency/packet loss issues is by turning on QOS and lowering the download limit by 5mb from your max line capacity and also lowering the upload down 1mb from your max line upload capacity. Then run the bufferbloat test again at waveform.

The screenshoot from the test has been uploaded 

  @MAtef Yeah just as I suspected! cap your download and upload speed using QOS settings as suggested and try the test again.

Cap download to 14 and upload to 2 just for experimental test

Click on advanced TAB to see QOS setting

  @Stevie-J 

i followed your steps and try the game but unfortunately the same result :( 

  @MAtef  Well you made a big improvement in regards to latency and packet loss issues.

Are you gaming on the PC with PUBG-mobile or using it on ur mobile.

  @Stevie-J  I am using IPAD Pro 2020

  @MAtef maybe with the QOS, find the IPAD IP address and put it into high priority section , other devices place in LOW and have the QOS sliders set to 

High 85% Med 10% low 5% see if that helps.
