If the plunger of the switch is fully depressed when you get that reading, yes. That much resistance would limit the current to the starter to less than 4 Amps at 12V. The starter needs maybe several hundred Amps to turn the motor. You should read at or near 0Ω with your meter when that switch is good. Most of the resistance you would be reading would be in the meter leads and their connection to the terminals on the switch.
That said, some folks have had some luck cleaning the switch by soaking it in some kind of cleaner. I have not tried that, and would not recommend doing that as it would be only a temporary fix at best.
