It is still however true to say that the Typhoon's basic structure was not designed to take the stresses of CATOBAR operations whilst the Rafale even with a lower weight was from the outset.
I agree. Rafale was designed from the start as a Naval fighter capable of carrier operations, with not only the necessary structure, but also the necessary over-the-nose sight lines, low speed handling, EMI performance, corrosion resistance/prevention, and other factors unique to naval aircraft. Adding those features after the fact to Typhoon would make it a very different airplane. The only aircraft (that I'm aware of) that started out land based and was successfully converted to carrier operations was the subsonic Hawker Siddeley Hawk which Douglas successfully turned into the T-45 Goshawk. But that was a pretty simple trainer and even then, it required BAE and Douglas to do an extensive redesign of the basic Hawk 60.
