I know that equilibrium constants are a ratio of the products to the reactants(in terms of their concentration) and we say when the system is at equilibrium the constant equals 1

this must mean the concentration of the reactants and products are equal for the system to be in equilibrium.

but I thought equilibrium ment a constant concentration due to the same rate in both directions not equal concentrations so why does the constant have to equal 1?

This is not correct. That is where you are going wrong.
The range for Kc is roughly
Kc < 10^-10 = reaction does not happen (product concentration too low to be detected)
Kc > 10^10 = reaction goes to completion (reactant concentrations too low to be detected)

Kc from 1 to 10^-10 equilibrium lying to the left hand side.
Kc from 1 to 10^10 equilibrium lying to the right hand side.

Somewhere between 10^-10 am 10^10
