That's just plain nonsense, and reveals that you've never actually supported 100 or 1000 laptops at once and become familiar with real-life failure rates of PC laptops from 2005-2015 vs. Macs.
If you have good statistics on real-life failure rates between Macs and ThinkPads/EliteBooks that contradict me (hopefully going past 2015, when Mac build quality really went down), by all means share them. I don't work in IT support and never claimed that I did.
