Some life insurance ads claim “you cannot be turned down.” What’s the catch?

Such ads are for “guaranteed issue” policies that ask no health history questions. The company knows it is taking a risk because people with bad health could buy their policies. The company balances the risk by charging higher premiums or by limiting the amount of insurance you can buy. The premiums can be almost as much as the insurance. After a few years you could pay more to the insurance company than it will have to pay to your beneficiary. Such policies may offer only the return of your premiums if you die within the first couple of years after you buy the policy.
