Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
"do I have word office with Microsoft 365 basic subscription?"
You do not. Microsoft 365 Basic does not include desktop apps like Word, Excel, and PowerPoint.
With Microsoft 365 Basic you get:
1- Outlook on the web and mobile, with ad‑free email and a calendar; and
2- OneDrive with 100 GB of cloud storage plus ransomware protection and file recovery.
For more details, see Microsoft 365 Basic.
However, everyone is able to use Word 365 on the internet for free. It does not have the advanced functions of the Word 365 desktop app, and all your documents will be saved to your OneDrive, but that might be perfectly fine for you.
