Does a valid number mean the person is on WhatsApp?

No. Everything above concerns format, which is a separate question from whether an account exists. A correctly formatted Spanish number can belong to a landline, to a newly issued SIM, or to someone who has deleted their WhatsApp account, and in each case the link will open and report that the number is not on WhatsApp.

To find out, open a chat link for the number and see whether WhatsApp starts a conversation.
