Both statements are correct, within their contexts.

The default *interactive* shell for user accounts is /bin/bash.

The default /bin/sh symlink (for scripts using #!/bin/sh, etc.) is dash.

The author of a script chooses whether the shebang says #!/bin/bash
(which makes it a bash script) or #!/bin/sh (which makes it an sh script).
The languages are different.
