What a mean thing to say to someone. I've been telling people the exact opposite for years - with enough time and motivation, anyone can get into FAANG companies, it's just a question of how much time and energy you want to dedicate to that.
Contrast this with becoming an astronaut or a gymnast, or a tennis player, or anything that requires you to acquire physical skills starting at a very early age and do it for decades.
I've been almost 10 years at FAANGs. There's nothing special about me. My GPA was 2.75. I suppose I can code and at this point I have some experience, but I'm no Carmack.
