The difference is with drainage, aeration and particle size. Potting or container soil mix is one thing and designed specifically for that purpose. Raised bed soil is intended to be used for any purpose other than in containers. Typically, it will state that clearly on the label.

You can use it if you like, but your plants will not perform the same as they would in a proper container mix and there is a strong likelihood drainage will be adversely impacted.

The brand Harvest Organics Raised Bed Mix says that it could be used for containers on Lowe’s but I don’t know if I trust them

With looking at the product and its ingredients, It seems to be better suited for containers than it does for a raised bed! Although it does say to apply as only a top layer for a raised bed......

But it is not ideal for a container soil mix either but I guess it could be used in a pinch.

I have to assume that if you dig organics into it every year, it'll be fine. Regular garden soil isn't recommended for containers because, after a while, much of the organics disappear, leaving you with mineral clay, and drainage and aeration go to pot. So if you've planted a tree in your container, for example, you're kinda stuck. But with annual veggies, no sweat.
