Iron is abundant on Earth, including within the crust, where it's the fourth most abundant element (after Oxygen, silicon, and aluminium), roughly 5% by mass. And yes, considerably more prevalent in the core. Iron and oxygen account for roughly 32% of Earth's total mass, each, the largest proportion of any element.

Sure, not as abundant as silicates. But nowhere near as rare as gold, platinum, and rhodium. Or even copper, silver, or lead.

There's even a fair bit of it flowing though your veins and arteries right now.
And yes, the major ore deposits are old. Most are BIFs (banded iron formations), and date to 1 bya or 3.5 bya, laid down by early oceanic algae for the most part.
Sometimes it's more than fine to allow a slight exaggeration to pass without litigating it to death.
