Single ICBMs can absolutely be intercepted, but the easiest they are to intercept during the launch phase where they are still accelerating, aka close to the launch site. An ICBM in its final phase of flight that's falling towards some random city... way harder. But yes, the nuclear threat relies on there being multiple ICBMs, with decoy warheads that are also launched so that you never know which one is the real bomb.
