Normally yes.
When there is a needed space is needed for archive logs, flashback logs are deleted.
But there is a hard limit for this and that may be an issue when you produce archivelogs in a very high frequency. That hard limit is  _MINIMUM_DB_FLASHBACK_RETENTION value. The default is 1 hour.
See MOS note -> FRA: Flashback logs are not being deleted when space is needed for archive logs (Doc ID 1481739.1)
