Hi,
Unfortunately the Family Microsoft 365 does not contain SharePoint, if you want to practice SharePoint you might want to implement a lab on-premises or on Azure, here's some information:
SharePoint Farm for Development Testing
https://docs.microsoft.com/en-us/azure/architecture/solution-ideas/articles/sharepoint-farm-devtest
If you decide to deploy a SharePoint lab in Azure, you can find SharePoint Server trials in the Azure Marketplace, you can also choose to create a small, medium or large farms.


However, if you're just starting out with SharePoint I also suggest you visit the SharePoint community, they will be able to answer more of your questions there.
(Please don't forget to mark helpful replies as answer, thanks!)
Best regards,
Leon
