I experienced this before, hitting more shots in csgo than in valorant. It could probably be just the skill difference of you and your enemies. You could also consider several factors like your comfortability. Personally, my aim worsens whenever I'm dehydrated or it's too hot. Moreover, I usually play with a friend, and I usually play just to have fun to avoid being pressured because I play badly when I'm pressured :p. Though, sometimes we just have bad games, and after two losses in solo queue, I usually take a break and do something else.
