A full beginner, which you aren’t, shall start maybe around 60k. But here, as many other go servers, displayed ranking starts around 25k. So it’s true that a 25k here can be of quite various strength. Now most will advise you to not care on rankings as beginner, wait to be approaching SDK (9k or better) levels for that.
You may look at this thread among others for some debates on beginners rankings on OGS. Note that we went through quite some updates through the years so be careful when consulting older threads on this subject!
