What does clear cache mean on tik tok?

What exactly does ‘Clear Cache’ do on TikTok? I’ve seen the option but I’m not sure what it actually does. Will it delete my drafts or liked videos if I use it?

Clearing the cache simply erases temporary data that takes up unnecessary storage on your smartphone.
The cached data includes your pre-loaded profile information and watch history.
Drafts and liked videos are not affected by clearing the cache.
Over time, TikTok will accumulate cached data again from your watch history and app usage.
