It does have armature resistance.
Right now a DC engine is begun the armature is stationary and there is no counter EMF being produced. The main part to cutoff beginning current is the armature resistance, which, in most DC engines is a low esteem.
An 'armature winding' is the rotor winding, and the 'field winding' is the stator winding.

A motor with large windings will have greater shunt resistance than armature resistance due to the sheer amount of copper wire it must travel through. The gauge of the wire also plays a part in this process.
why armature resistance is very low as compare to field resistance in dc motor

On a multimeter, a high resistance would indicate a high Ohmic value and a low resistance would indicate a low Ohmic value. Specific values would be relative to device you are measuring.
Without a mechanical load the motor accelerates until the back-emf generated by the armature nearly equals the supply voltage. On load, the speed drops and the current rises until the power taken from the supply balances the mechanical power supplied to the load. If the armature has low resistance, the speed drop under load is not very much, so speed regulation is better if the armature resistance is lower.
The resistance value of gold is very low, typically around 22 microohms at room temperature. Gold is an excellent conductor of electricity due to its low resistance, which makes it useful in electronic components where low resistance is important.

yes
we can measure the resistance of the motor by using voltmeter ammeter method of by directly using a multimeter across the armature terminals of the motor in voltmeter ammeter method we should use a less value of dc voltage to find the resistance
