On Android 8.1 when i update my system it says 2. 20 grams of traffic. Does it reduce the memory?

This is how much the update itself weighs. If it exceeds the volume of the current firmware in the smartphone, it is possible, but unlikely that the volume will decrease a little.
Why unlikely: to reduce:increase the space occupied by the firmware you need to re-partition the memory. It is not easy to do with just an over-the-air update. And the vendor itself doesn't need it because it may cause malfunctions. + You need to perform a full reset of your smartphone. And according to the terms of the OTA (updates over the air) memory cleaning should not be.
