This comes up too often and it's been almost 6 years of Valorant and I still see people debating this wrong... The argument goes something like this, person A, uses Aim training but doesn't see the same results of their labor in Valorant and posts it on an internet forum. Person B jumps in and says that spending in time in an aim trainer doesn't make you good. Person C says that their personal experience is blah blah blah.
First, Valorant has spread or recoil. With most rifles, you are dealing a .2+ degree spread issue when aiming. Spread can be compounded by moving while shooting (insert deadzone discussion description) which increases your spread dramatically depending on the movement action (walk, run, jump) and the weapon you have. So even practicing aim training is going to be detrimental because it will teach your brain that you need to hit the center of a target. In Valorant, because of spread at distances, sometimes the headshot cursor placement is below the head.
Vandal spread (also I don't care if these are accurate anymore and yes I mapped these out for all the guns in Valorant)

Second, Aim trainers do not teach you about gunplay optimization and positioning. Gunplay optimization is your planned start of a fight and the distance at which you take fights. Guns in Valorant are situational. This is based on spread and damage distance.
The connecting fabric is positioning. It's digesting angles at a process which you can actually handle. Good Valorant doesn't look like most highlights you see on X or Tiktok. Good Valorant is methodical, intentional and a bit of movement chaos.
Conclusion:
Use Aim Trainers to learn mouse control. Learn Valorant mechanics to apply mouse control to Valorant mechanics. Use brain to stop arguing about dumb things you pretend to know about <3
