If you're not stabilized by 500 feet, including speed, you have to make a go-around.
Now, if you press the TO/GA buttons then, no matter what, you'll never touch the runway.
Touching the runway during a go-around may happen if you initiate it at, say, 100 feet or lower. This might happen because the runway is blocked, or a windshear is encounted, or such alike. But these low-initiated go-arounds are flown from a stabilized flightpath, by definition.
Otherwise you did not have reason to be there in the first place.
