No, equilibrium doesnt mean same concentration at both ends. Equilibrium means rate of forward and backward reactions become equal.
Chemical equilibrium is reached when the rates for the forward and reverse chemical reactions are equal for a chemical system. Or you could say when products are being made as fast as they are breaking down to form reactants again.  The concentrations of products and reactants are generally NOT EQUAL
