In general you can't trust/take seriously whatever the management says, except for 1. specific information reflected in the HR systems and 2. the specific tasks/deadlines/etc. assigned to you and the related progress/delivery/etc. discussions.

Specifically, when it comes to public praise, the manager publicly praising his team/dept/org is actually praising themselves while supposedly being publicly modest/coy by not explicitly praising themselves, and this is why management loves making those praises.
