What recruiters make on each placement depends on the salary you'll fetch. It's in their interest to make it as high as possible, and know exactly what the market rates are.

However, what recruiters do understand is what you'll fetch depends very much on your attitude and confidence. You act like a lamb, you'll be sold like a lamb. But that still means they know exactly what you will be able to get.

Good recruiters will coach you to increase your market value, but even the shitty ones know their numbers.
