Yes you're definitely on the mid-high DPI spectrum of FPS gamers. Don't let this news make you think you need to change it however, as there are many professional players who are extremely good with high DPI/sensitivty (much higher than you, for example Ghostfreak66 was a R6 pro who plays with 4k DPI).
In almost every competitive FPS, players often use low DPI and low sensitivity, with a combination of wrist and arm movement. There are many reasons for this, one of the biggest being recoil patterns (like CS/Rust). Another being the fact that they started gaming with standard 400/800 DPI mice, and they got used to and never changed it.
Its not just the sweaty chads who use low settings, its preference. If you can hold steady aim with no jitter when flicking, tracking, spray-transferring etc. then you have no real reason to change. But there are a lot of players who come from MOBAs or RTS games where they never really cared about these settings and found it easier to pick up the nuances of FPS gaming and improving their aim after lowering their DPI. Myself included, I played LOL for 5 years with 1600 DPI and when I started playing Rust and couldn't aim to save my life, I moved to 800, then 400 and lowering my sensitivity in steps.
What most people do when they're trying to find the right settings is place your mouse in the default position (the center of your mousepad or whatever), and try to do a 180°. If you can comfortably do a 180° with extra space on the left/right of your mousepad then you're free to reduce the sensitivity until your at the end of your mousepad or comfort zone.
In the end, none of this **** matters. It's all muscle memory.
