Hello.
Are STM32 parts distribution only B2B?
Digi-Key and Mouser are out of stock yet.
Quite a few items fall into this category.

All production is going to fill orders.
Retail Distributors will get whatever they ordered much as anyone else would. They have trouble predicting random demand that shows up, plus other businesses grabbing any parts that do show up there to shorten their own wait for parts.
The industry has moved entirely to build-to-order over the last several decades, and away from warehousing vast stocks of a few ICs.
Don't expect the situation to improve dramatically in the next 12 to 18 months. Plan accordingly.

STM32 parts are not B2B only.
There is a chip shortage which has been happening for ~2 years now. More popular chips are the most affected. Find what you can, or order now and plan accordingly to wait.
