•♥•Event Goal 4/25 : Open Any Chest In The Dragon's Delectation Tower 4xs...isn't accurate. Opening a Victory Chest doesn't contribute to this Quest's Requirement.•♥•
Unfortunately, that is correct. Win chests don't count for those goals, only for the gold or girls' cards goals.
The 'any chest' part probably refers to the level of chest in your chest slots at the bottom; common, rare, epic etc.
