Quite right. But that’s because “Queen” is an overworked word - it means both “Female ruler” and “King’s wife”. “King” never means “(ruling) Queen’s husband”. (You can say “Queen Consort” or “Queen Regnant” if you like.)
…And of course it also means “late King’s widow”, of which we’ve had a couple in the last century alone.

England has had two Kings Consort, both on very unique circumstances, and it’s unlikely that either circumstance would ever come up again. (Great Britain only had the second instance.)
First, Felipe II of Spain, son of Holy Roman Emperor Charles V (and hence grandnephew of Catherine of Aragon) was married to his first cousin once removed, Mary I Tudor, daughter of the aforementioned Catherine and Henry VIII. As King of Spain, the Lowlands, the Hispanic realms beyond the sea in America, and God-and-historical-geographers know what else, he was a King in his own right. He greatly influenced what his wife did while on the throne, and after her death claimed the throne of England for himself under the “crown matrimonial” – a claim duly ignored by all and sundry outside his own realms. But he was King Philip, consort to Queen Mary, for 5+ years.
Then William III. This one gets tricky. If James II and his Catholic infant son are excluded from the throne – the results of the Glorious Revolution of 1688 – then the three legitimate (Protestant) heirs are, in order, Princess Mary Stuart, elder daughter of James II; Princess Anne Stuart, younger daughter of James II; and William, Prince of Orange, Stadtholder van der Nederlands, son of Charles II and James II’s sister. But Mary is married to William, and he is the leader of the alliance against Louis XIV that England’s freedom depends on. Net result was that after negotiation, it was agreed that William and Mary would ascend the throne jointly, as co-monarchs, and that Anne would resign in William’s favor her right to succeed Mary – but only as regards him – so that either Mary or William will be unquestioned monarch if either outlives the other (as William in fact did) and Anne will be heir to the survivor (a child of the couple being unlikely). But while Mary was heiress of line, William became King in his own right as her consort and as next in line after her and her sister.
But yes, “Queen” may mean either “King’s wife” or “female monarch.” For a few months in 1952-53, England had three Queens: Mary, Queen Dowager since 1936, widow of George V; Elizabeth, the Queen Mother, widow of George VI; and Elizabeth II, granddaughter of Mary and daughter of Elizabeth, the reigning monarch.
