>It's like telling people "well, you know, if you eat more than you need to, you'll gain weight". Duh, not helpful.
It is a foundation to work from. Far better than believing that you can cheat thermodynamics, which is generally the alternative.
There are some fringe cases and nuances, but I have never heard of one that was relevant. Do you have a use case where deviations would matter?
Absorbed calories don't match label calories, but weight loss and gain are studied in terms of label calories, so it is irrelevant unless you are doing chemistry or particle physics.
Labels could be in terms of arbitrary moon units instead of calories and it would still be true. Weight loss is a function of moon units in and moon units out.
