Tilling, in gardening, usually refers to lifting spadefuls of soil up and out of the ground, turning them over and breaking up the clumps. It's like a kitchen aid stand mixer on your soil.
Aeration with a broad fork doesn't lift the soil out of the ground and definitely doesn't break it up and redistribute it. It just creates a few pockets of stretched space by inserting a fork and wiggling a bit. Yes, small pockets are disturbed by the fork but mostly the soil stays as it was.
