Wait statistics, in the context of SQL Server, refer to the amount of time that a query spends waiting to access data in the database. When a client application requests data from the database, the request is placed in a queue and the client application must wait for its turn to access the data. The time that the query spends waiting is called a “wait” and is tracked by SQL Server. This information can be used to identify potential performance bottlenecks and optimize the performance of the database. Wait statistics are commonly used by database administrators to diagnose and troubleshoot performance issues in SQL Server.

The SQL Server PREEMPTIVE_XE_TARGETFINALIZE wait type is a type of wait that occurs when a session is waiting for a target to finish executing an Extended Events event. This type of wait typically occurs when a session is trying to create or alter an Extended Events session or target, or when it is trying to stop an Extended Events session or target.
When a session is waiting on the PREEMPTIVE_XE_TARGETFINALIZE wait type, it means that it is unable to proceed with its current operation until the target has completed its work. This can cause delays and slow down the overall performance of the SQL Server instance.
To troubleshoot and resolve issues related to the PREEMPTIVE_XE_TARGETFINALIZE wait type, it is important to first determine what operation is causing the wait and then investigate why that operation is taking a long time to complete. This may involve looking at the Extended Events session or target that is causing the wait, as well as any queries or processes that are running concurrently with the operation.
In some cases, it may be necessary to optimize the Extended Events session or target, or to adjust the workload on the SQL Server instance to reduce the occurrence of the PREEMPTIVE_XE_TARGETFINALIZE wait type.
Overall, the PREEMPTIVE_XE_TARGETFINALIZE wait type can be a useful indicator of potential performance issues related to Extended Events in SQL Server, and can help DBAs and developers identify and resolve those issues to improve the performance of their databases.
