I have 1853 rating, 17 games - 15 wins, 1 draw and 1 lose. Which category I have? 2 or 1 category?
That category system is really meant for over the board tournament chess, where playing conditions are controlled. That being said- it's still too early to say.
The fact that you have only lost one game shows that your current rating is probably still not very accurate. That is also indicated by your Glicko RD (rating deviation) of 86, which estimates that your true rating is somewhere in a 2 x 86 point range around 1853. (See the article linked below for more explanation.)
Keep playing until your rating settles a bit. The RD will go down to 25 or so, which means that there is a 95% chance that your rating is accurate within a 50 points range.
