Yes, exactly. That is, a small piece of glass is less likely to puncture the tube or work it's way in and cause a flat. However, nothing will help if you ride over a thumbtack, for example.
The price you pay is higher cost, some extra weight and perhaps higher "rolling resistance."
I had some "armadillos" on my bike, but I wanted something lighter, and I have the ultra gatorskins on now. They are good, but the sidewalls aren't very resistant to problems.
Flats are weird. You can go years without one, then have five in a week.
Often glass or debris will stick in your tire a little, then gradually work its way into the tube as you ride. So two things you can do are (1) after riding over some glass, put your gloved hand on each tire (as you're riding), to knock pieces off (takes practice), and (2) examine your tires after each ride to see if anything is stuck in them.
