At the very top of the help output:

GNU bash, version 4.4.18(1)-release (x86_64-pc-linux-gnu)
These shell commands are defined internally.  Type `help' to see this list.

Thus, they are internal.

If you see all the internal command in ubuntu then type 'help' command in terminal

Or

Use 'type' command to check ..

eg. $ type type

$ type is a shell builtin

Of interest: `type echo` and `which echo`. Follow this by `type -a echo` – WinEunuuchs2Unix Mar 19 '18 at 01:12
