Traction and stability control vs awd

Thank you.
Okay, once I get a good set of winter tires then I would not need AWD for driving on plowed road. This is how I understand your answer which i greatly appreciate.
I currently drive a Mazda3 which is terrible in any inclement weather. I have also had some “unable to diagnose” problems that have made me uneasy in the past year. I am not new to winter driving but since this past year I feel as though I need to drive a tank.
