Yes, but...
No, it only means the capacitors are unpolarized.
Unfortunately, the digital youngsters here have never seen a real meter, like the Simpson 260.
As you can see by this Amazon page, they maintain their value. For good reason. No digital DVM can do the same things as the Simpson. They are simply too slow.
I can test any capacitor with my Simpson. If you watch the needle when you touch the leads to the capacitor, you will see a small dip.
