Help with delaying a counter animation

I have a page with a bignumbers section with some prefilled static numbers that get replaced with live stat numbers from a json query from my clients database.

We want to animate those numbers, using counterup2.js or something similar, but when i add the counter code, it animates the static number that is barely seen before being replaced with the updated numbers.

I tried $(document).ready before function, i tried setTimeout() but i cant make it animate the real numbers…

I am really not a dev, so i try to research a lot and copy/paste and modify solutions, i cant really write/troubleshoot code… if someone can help it would be much appreciated.
