Prevented, not necessarily. TC and ABS both come with warnings essentially to the effect of, it's the rider's job to prevent loss of traction. That being said, these systems exist because sometimes people make mistakes, like forgetting you've got a new tire, no biggie. It's important to recognize that TC is primarily reactive, it goes to work after a loss of traction, very quickly, but still after. The TC light can be easy to miss, especially if you're in a situation where it's working. If you started letting off the gas when the system engaged, you might not have noticed the difference; and if you pulled in the clutch the system would have been limited in what it could have done anyway. In either case, that's essentially the same as you having the skill not to need the system. It's also entirely possible the system did its job and that was the difference between pants filled with **** and pants shredded on the asphalt.
If you'd like to test it, try to wheelie on TC3, about all you'll get is a little bunny hop. Or your new tire will break loose, either way you should see the TC light blink and feel the power loss.
