See the following from Access and manage your files in iCloud Drive - Apple Support for information on what iCloud Drive can do:
iCloud Drive lets you securely access all of your documents from your iPhone, iPad, iPod touch, Mac, and Windows PC.
When you sign in to iCloud, you have access to iCloud Drive. With iCloud Drive, you can keep files and folders up to date across all of your devices, share files and folders with friends, family, or colleagues, and more.
You can store files* in iCloud Drive as long as they're 50GB or less in size and you don't exceed your iCloud storage limit. If you need more iCloud storage, you can upgrade to iCloud+. With iCloud+, you can also share iCloud storage with your family, without sharing your files. Learn more about prices in your region.
