In all fairness, there is a lot of documentation in veracrypt's manual about how to properly hide a hidden partition, and how it's circumvented.
Most of them rely on knowledge of the encrypted container over time. A single point in time is unlikely to reveal a hidden partition, but if you are being monitored that is possible.
Please note that backups or wear leveling on an SSD, or just the TRIM command not deleting stored data can provide those points in time. Hidden partitions work best on magnetic drives.
