I bought 200 gb space in icloud but still my phone says i dont have enough space my phone is 64 gb iphone x

I would like you to realize and know one important thing and that is that there is NOTHING that you can do to increase the physical storage capacity of your iPhone. Your iPhone's storage capacity will forever remain the same as the day you bought it. 

You can purchase ➔ iCloud Storage from Apple where you create and save your iPhone backups and synch (Not Store) your Messages, Photos, Contacts, Calendars, Notes and Reminders. Note that iCloud Storage is NOT an extension of storage capacity of your iPhone. Just wanted you to know some facts.

Having said that, you can choose to Optimize Storage on your iPhone for all the Photos. What this action will do is store your original quality photos on iCloud and a small size photo on your iPhone. This takes up less space on your iPhone while maintaining the actual size on iCloud. This will free up space on your iPhone while making good use of iCloud. If you would like to try this then open Settings ➔ Photos ➔ Optimize iPhone Storage : Ensure that this option is chosen and has a checkmark on it.

Just adding additional storage in iCloud does not increase the available storage on your iPhone. The support article you came here from should provide you with that information.

However, there are still things you can do to better manage your iPhone's storage:

• Manage your photo and video storage - Apple Support
• Delete music, movies, and TV shows from your device - Apple Support
• 5 Easy Ways to Free Up Storage Space on Your iPhone - Tom's Guide

It will depend on the amount of photos you have on this phone. They will have to be synced to your iCloud account, and replaced with smaller ones on your phone. In turn, your Internet speed will also determine the amount of time that would take.
