I'd be surprised if he said that because it's absolutely not the case (and I mean no disrespect to Clapton in saying that).
Clapton emerged out of a whole scene of British players who had discovered and were inspired by the blues. The key sources here are not so much Clapton, but John Mayall and the Yardbirds. Mayall probably got "turned on" to the blues by Alexis Korner.
What is beyond doubt is that in the late 50s, early 60s the blues and the great blues players (Muddy Waters, the Kings, Elmore James etc) were far better known in Britain than in the USA.
Joe Boyd tells a tale of how in the early 60s he was at a Chuck Berry concert in the UK. He saw a familiar shadow in the wings and said, more to himself than anybody else, "That looks like John Lee Hooker". The teenagers standing around overheard and the whole place went crazy - they all knew who John Lee Hooker was, and the only way for Berry to get things under control was to call Hooker on stage to take a bow.
Pink Floyd are named after two rural blues players - Pink Anderson and Floyd Council. An early inspiration to the Stones (and this is very early, before they got even a sniff of a recording contract) was Elmore James.
Peter Green, Rory Gallagher, Jimmy Page, Syd Barret and Jeff Beck (for starters) were contemporaries of Clapton's and would have been familiar with the classic blues canon.
Even a lot of significant acoustic players in the late 50s, early 60s British scene would have had significant inspiration from the Blues - John Renbourn, Bert Jansch, Davy Graham, Martin Carthy for starters - with a key figure there being Big Bill Broonzy.
