"Center" blocks are defined in the manual, along with their syntax.
There is nothing surprising.

Moreover, there is no such thing as a "Right" block. Or, more precisely,
this falls into the special block category, which is handled differently
in each export back-end.

This reference card is not an official reference card.

In any case, let me insist again on the following point: you can use
"#+begin_right" in HTML to your heart's content if you define the
appropriate CSS property.
