The ‘if you feel thirsty you are already dehydrated’ thing is a myth spread by drill sergeants and gym teachers.
A number if things can trigger thirst, including but not limited to dehydration.
Signs of dehydration are nausea, headaches, dry mouth and throat, reduced blood pressure, dark urine.
The tl;dr is you should drink when you are thirsty- not force yourself to drink when you are not.
Edit: To clarify, if you have symptoms of dehydration other than thirst you totally should have a glass of water even if you don’t want it. Sometimes your body is weird like that.
