And they are somehow managing to do so currently without licences.

One thing to consider is how much effect licensing has on car safety anyway. Mexico city has no test requirement at all, you just pay for permission to drive rather than sitting any test, while Peru has more road deaths per capita, despite needing a practical test, written test and medical certificate before you get behind the wheel.

so what is the conclusion here? Road tests have no positive impact on road safety because Mexico City has fewer accidents than Peru?

No, just that the effect on safety seems minimal compared to other factors.
