When you believed in Jesus you became a special class of person that the Bible calls someone who overcomes the world. You get this status because Jesus utterly defeated the devil. Jesus defeated him so thoroughly and so publicly that every angel and demon saw that defeat. Your status in Christ gives you that same victory over the enemy and over the world. You are an overcomer! Walk in the victory Jesus won for you.
Who is he who overcomes the world, but he who believes that Jesus is the Son of God?— 1 John 5:5 (WEB)
