If I clear cached data will my photos or my game progress also be clear?

No, If you  clear cached data will your photos or your game progress also be clear:

• Cached data refers to files, scripts, photos, and other multimedia that are saved on your device after you first use an app or visit a website. This information is then utilised to gather information about the app or website rapidly each time it is accessed, lowering load time.
• Caching is the process of saving cache data or cache files as history on a phone or web browser in order to improve the user experience on subsequent visits to a website or app.
• Because cached data is merely considered 'temporary storage,' it isn't necessarily important. It does, however, exist to enhance the user experience.
• Images, videos, and even text take a long time to load on a page. When this data is cached, we may restart the programme or go back to the page knowing that it won't take nearly as long.
