Open Question: With a NVQ Level 2+ How long will it take for me to be eligible for Warehouse manager?

I'm about to take a NVQ Level 2 (Or higher) college training course in warehouse and logistics. I'll be training in a warehouse for 35+ weeks. Would I be eligible to take the place of warehouse manager? If not how long will it be, i read that it varies on the employer, I was searching through jobs and they said warehouse experience would be an advantage but not necessary. Would i stand a chance do you think with that qualification on me? Whereas most other warehousemen and women aswell as warehouse managers dont have that qualifications (As far as i'm aware, its only a recent qualification that's come into the system.
