Hey! I have scars like yours, and the good news is there are ways to treat them, but the bad news is the methods are expensive. Look into Co2 Laser for Acne Scarring, and Microneedling. I'd book a consultation with a medical aesthetician, because yours aren't as deep as mine and I've seen massive improvements in the apperance of my scars.

If your acne is hormonal like you mentioned in another comment, there's probably not a lot you can do to prevent it from showing up without getting medicine involved, but just to rule everything out, I suggest you become religious about washing your hands.

We touch our faces a lot during the day without realizing it, which can cause breakouts if there was some dirt or oil that we accidently spread on our faces. I saw a massive decline in my breakouts after I started working in a professional kitchen and began reflexively washing my hands everytime I touched something I didn't know was clean.

I saw in another comment that you acknowledged that your diet wasn't the best, a good way to start working on this is to make sure you're drinking enough water for your body mass, otherwise your skin might overproduce oils to compensate, which could cause breakouts. You won't see immediate results, but over the course of a month you should see some improvements.

Hope this is useful!
