In helm <TAB> open the action buffer if the source have more than one
action.
helm-M-x have only one action, if you use helm-mode the regular M-x
command will have only one action also.

A typical use of helm is typing something in minibuffer to narrow down
the completion buffer and moving in this buffer with arrow keys or C-n/p
to select the candidate you need.

So to reply to your question, there is no TAB completion in helm because
the helm-buffer is the completion result itself.
