Pc vs Console players

Hey guys , I used to be an avid Battlefield 1 console gamer . I recently got the game for my pc , and I have really been struggling . On console, I used to average an easy 3K/D , but on pc I barely scrape the 1K/D ratio. Many games getting less than that. So now I am wondering , is it because pc players are much better than console players ,or is it because I was spoiled with aim assist on console and do I just need to become more skilled at aiming ?

Am I the only one with this frustration or has anyone else experienced the same ?
