It could be the way you're interpreting, but I suspect what she means is that she didn't go through and verify the exact measurements and timings in the recipe. There are simply too many variables involved in (non-baking) recipes to produce an exactly reproducible result - your ingredients might be different sizes, your "medium" heat is probably not their medium heat, differences in produce might affect the amount of salt/sugar you need to add, etc. Also, when scaling a recipe up or down, you won't actually want to scale things linearly - it generally takes much longer to cook a large portion than it does a small one, or it feels silly to use 1/8th of an onion, etc. Most of these can be solved through measuring by weight, but that's annoying unless you're baking.

So the recipe is really just some rough proportions that have probably never been cooked exactly; you are expected to make adjustments. That's why I find video recipes super helpful - you can see how each step is supposed to look, so if the timings in the recipe are wrong you can still adjust on the fly. And tasting as you go is always a good idea too.
