On that html page, yes.
But the stylesheet could also reference a div#para1 that is in the
html on a different page on the same site. Then #para1 would apply to
both the paragraph on one page, and the div on another. Adding the p
will prevent that.

For myself though, the reason to write p#para1 instead of just #para1,
would be that by looking at the stylesheet, I can instantly see that
it is a paragraph that's being referenced, not a div or a span or
anything else.
