If that router has a 1Gbit port it’s physically impossible and likely a measurement artifact.
Actual speed on a 1Gbit port is something like 940Mbps according to experience (I believe the theoretical max there is 970).

That's pretty typical. It's similar in the States: Spectrum, for example, generally overprovisions their connections a bit just because customer support is expensive to provide, and when things [ideally] work even better than advertised, support costs go down.
And on that ISP side of things, it's a software-defined limit; it's just a field in a database or a config file that can be tuned to be whatever they want it to be.
But the fellow up there says that they got 1.2Gbps through a Mikrotik Hex S: https://mikrotik.com/product/hex_s
And that's just not possible*. The E60iUGS Mikrotik Hex S's own hardware Ethernet interfaces are 1000BASE-T, and it's simply not possible to squeeze more than 1.0Gbps through a 1000BASE-T interface. (It does also have an SFP port that it has one of is branded as "1.25Gbps," but reality is that it, too, is limited to no more than 1.0Gbps of data transfer.)
*: Except... the 2025 version of the Hex S, E60iUGS, does have a 2.5Gbps SFP port that could be used as an ISP connection, and a much-improved internal fabric compared to the previous version. But the rest of its ports are just 1Gbps, which suggests a hard 1Gbps limit for any single connected LAN device.
Except... Mikrotik's RouterOS allows hardware to be configured in many, many ways -- including using LACP to aggregate ports together. With the 2025 Hex S, an amalgamation could be created that would allow a single client computer to get >1Gbps from an ISP. It might even be possible to be similarly-clever with the previous version of the Hex S. But neither version will be able to do end-to-end >1Gbps without very deliberate and rather unusual effort.
Not sure what GP’s situation is, but I have a 100Mb/s fibre internet package but all hooked up to 1Gbps capable equipment on my side.
My typical speed test results are around 104Mb/s. Before being upgraded, on the 50Mb/s package I was getting 52Mb/s.
My suspicion is that fibre network operator (OpenServe in South Africa) applies rate limits which are technically a little above what their customers are paying for, perhaps to avoid complaints from people who don’t understand overheads.
