Your luggage will be checked through to your final destination in this case
As long as the airline is willing to sell you that connection, they think you will make it, and they have a strong incentive to make sure that you do, because otherwise they have a duty of care: rebook your as soon as possible, pay for a hotel ...
Citizens of Cameroon do not generally need visas for airside transit to change planes in the Schengen Area, as long as you do not need to pass through immigration.

At the airport, you can reduce your risk: Stay away from people (5 meters), especially coughing people, don't touch anything, wash your hands after touching anything.

I've not been to this airport myself, but based on the terminal maps available from the airport website it seems that your friend is correct.
The diagrams are low resolution, but I'm just about able to make out the captions. The map of the first floor isn't relevant to your question. The ground floor shows two arrivals gates (top-left, marked by a box with ...
