Overwatering... another hugely misunderstood term.
What overwatering means is having standing water in your pots. Plants dont need water plants need moisture. Big difference here. If you have standing water on a root it immediately begins to drown. When you water from the top and it runs out the bottom it creates suction on the soil. As the water sinks it pulls air in behind it. Roots breath oxygen and foliage breathes CO2.
In a pot that has perfect drainage such as a smart pot you cant overwater as the pot wont hold standing water. You can overflood though and start rinsing nutes right out the bottom.
You still need to keep in mind though that drying the pot out forces root growth to chase water. So only in full flower with perfect drainage can you keep your soil more evenly moist. If soil completely dries all microbes die. Microbes also get eaten and die of old age so every 3rd watering or so should be compost teas to add microbes if growing organically
