Not sure about winning but drones are the major factor in Ukrainian war. Style of warfare did change completely. You should probably listen to interviews with the soldiers on both sides. An eye opener.

As for attacking civilians being the goal:

[1] - "At least two people were killed, including a 22-year-old police officer who was named by authorities as Maria Dziumaha, and more than a dozen were wounded in the attacks, according to authorities..."

That is after more than 400 drones were used in the attack.
