Going back 29 years to the beginning of my career, I'd say maybe 50% of the graduates in my class, probably more, either were not cut out to be engineers or didn't really have any passion for it(or both).

I can't imagine what the ratio is now after everyone was pushing their kids into coding and every douchbag chasing a high salary tried to enter the field. Maybe close to 90%?

I can't imagine there is much of an issue for bright, passionate folks just starting their career if they can manage to communicate their passion and skills to a company. Sure, they might not go directly to a fang, but there are literally tens of thousands of companies who staff engineers and if I were new that's where I'd target to get started.
