What's wrong with guerilla fights

How many people have experience similar to mine?:

Say I'm fighting guerilla fights.

I am fighthing 25 fights, in each fight I fight with the same weapon as the opponent. We are both at 90% hit chance, but my actual hit is about 10-15% while my opponetents are hitting say 100% or 95%. That way I lose 25 fights in row.

What's wrong here? Is random machine broken or there is some widely spread hack that allow many players to get eternal advantage?
