Difficulty switching gears on a manual car

I have a manual Kia Rio 2016 hatchback 1.2L and I have so much difficulty switching gears (video provided, this is how my gears should be switched (the car is off), when I turn my car on this is how the gears switch, with some difficulty, its harder when I am on the road) I feel grinding when I switch to 2nd and 3rd gear, I got my clutch pumped, that helped for a bit, but then it went back to how it was. I never had this problem when I just bought this car in June, I could always switch gears smoothly, but when winter started I thought it was due to the cold, but that wasnt the case. So Im thinking should I get the clutch/gear discs replaced? I need some advice lol
