I have a MacBook Pro Retina 13" Late 2013 with PCIe SSD and over some months, my computer started to be much slower. I downloaded Blackmagic Disk Speed Test and got 190 MB/s for write and 460 MB/s for read. Every YouTube video shows around 650 MB/s and 715 MB/s for my computer model
How can I proceed?

When was the last time you shut your mac down completely??? Try that first.

Then do a repair disk in disk utility.

Make sure when you run the disk test you don't have lots of things going on in the background like downloading large files or other such disk intensive processes.
 
No idea then, dodgy disk may be the issue, could try running a hradware test or similar.

Are you using file vault or other disk encryption??

Oops just noticed it's a 128GB disk they do have worse results on speed as the amount of memory does make a difference to speed they are still a bit low though. 700 read and around 400 write are the expected for that size.

I'm guessing those videos are the 256GB or larger models that have much faster write speeds. Your 128GB model will be around half that or so. What you are seeing is totally normal.

Like Sam mentioned, if you have FileVault turned on, that will slow it some.

Here is my 2014 with the 128GB flash drive with FV on.
