Sharepoint is for organisational use. Organisations can create Sharepoints websites for a specific team or group of users with the organisation, websites for all employees within the organisation, or public websites.

Using Sharepoint organisations can also share data*within the organisation.

If you are a private user, Sharepoint is nothing for you. If you are using an Azure AD / Office 365 for Business or Enterprise account, your Azure admin*or IT department can tell you about Sharepoint services available for your organisation.
