Who can explain the difference ?

You could. Atleast if you get to terms with the different function op a Operating system and Firmware.
OS is ROS snd version 46.7.1
Firmware is used to start the router and ROS is running on top off that.
Those two can have different versions like a older BIOS in your PC and running the latest Windows 10 on it.
It is best to keep the Firmware for your router close to ROS version.
So when i upgrade the packages it doesnt upgrade the firmware itself?

No, firmware needs to be upgraded separately. On your screenshot with “Upgrade” button you can do it.
