Wins may be based on luck for rookies early on. It takes a lot of practice to get a win based on skill. There are many guides on blackout, so i'll give you my quick suggestions for a noob.
1. Sky dive into the dense areas that are not labeled on the map. Look for small houses and pick up a gun ASAP!
2. Pick up all the ammo you can and try to get at least 1 long-range weapon (sniper rifle) and a mid-range weapon (Assault Rifle or SMG).
3. Equipment is very useful too like grenades, molotovs, trauma kits, med kits, etc. but you might need to pick up a backpack to carry all that stuff.
4. Get as many add-ons for your weapons as possible, don't waste too much time swapping stuff out though.
5. Pick up perks and use them right away. Dead silence and paranoia are amazing, as are many others.
6. The eye of the storm closes fast so just make your way near it's center while scavenging very cautiously. Avoid using a vehicle unless the storm is coming on top of you.
7. If you see someone, only engage them if it's self defense or you know it will be a clean kill. Every shot fired in the map gives away your location and could end your life very quickly.
8. As the storm gets very small, move slow and stay on the edge of it, using cover often. Sometimes it's good to move in a circular motion around the bubble.
9. This is typically where you just listen for foot steps and snipe anyone you see. Let others fight each other and then pick off the winner if you get so lucky.
10. WIN!
