Scale is the point. These things are a lot cheaper to build than the drones Russia is using to attack Ukraine. And Russia doesn't actually have a manufacturing advantage because the Western Europeans are helping Ukraine. Ukraine is making weapons in places Russia can't bomb like Poland, Finland, and Estonia with EU money using an EU workforce.

Last year Ukraine churned out more than three million drones, and is on track to triple that this year. The model upon which this particular drone is based costs about $3k, so they can make as many as they need.

Nobody is saying this will win the war. What I said is it will allow the Ukrainians to intercept Russian drones cheaply. This is already forcing the Russians to spend more on each drone to make them harder to intercept, which is a victory in itself. If you have to put $100k into your drones to make them effective, you're not manufacturing drones anymore. You're making comparatively expensive cruise missiles, and you can't launch them in the hundreds every day without going broke.
