Which statementis definitely true about priorities in Jira?

Jira administrators can create and update global priorities, which are the default set of priorities available in each project. Project administrators cannot re-order, create, or update priorities in their projects, unless they have Jira administrator access. The same set of priorities is not always available in each project, as Jira administrators can configure priority schemes to assign different priorities to different projects. References: [Configuring priorities], [Managing Jira Projects Data Center and Server: Certification Bundle]
