This is how it is translated.

انتم tum
الا علوں Ghalib/fatiheh
ان Agar
کنتم tum ho
مومنین Momin/Iman valay

Complete Translation: Aur tum ghalib ho gay agar tum iman rakhtay ho.

This ayah was revealed in the aftermath of ghazva e Uhud. The Muslim community was sad and heartbroken at large. So the verse was revealed.

The context of the ayah (the ayah after this) points out that Allah is reminding Muslims that they should not lose hope and He is encouraging Muslims by pointing towards the victory of badr. Allah points out that if disbelievers did not lose hope after the battle of badr, why should you?

You can contextualize the meaning in the current scenario where Muslims all over the world are engulfed by the wave of disbelief in their own strength due to the immense power of non-believers. Hence, the role of the ummah should be directed towards a revamp of situation where we redesign our strategies and effectively prepare for the future despite having gloomy immediate past because Allah has destined us to win if we follow the right path. Hence, the Ummah should reshape the system by integrating the true spirit of sharia. This is what I can comprehend (in relation to question). Your views might differ.
