Hello and thank you for your question!
No, Confluence already has some templates by standard. They are like page templates, which can be used to create pages with specific content. In addition to that you can buy more blueprints at the Atlassian Marketplace. Also the Confluence admin is allowed to create own blueprints.
Please find more info about blueprints here: https://confluence.atlassian.com/doc/blueprints-323982376.html
If you have further questions, just let us know.
