我的异步方法真的是异步吗？

Question

函数AuditMarketStatusToDatabase确实是异步的吗？ InfluxDbClient.Client.WriteAsync是一种外部异步方法

        // main method
        // some code before
        AuditMarketStatusToDatabase(marketStatusPoints, database);
        // some code after

.

.

       private async void AuditMarketStatusToDatabase(List<Point> marketStatusPoints, string database)
       {
               await _influxDb.WritePointAsync(database, marketStatusPoints);
       }

       public async Task<bool> WritePointAsync(string dbName, List<Point> points)
       {
           IInfluxDataApiResponse response = await InfluxDbClient.Client.WriteAsync(dbName, points);
           return response.Success;
       }
