Sure, it is not the risk of a plane crash.
All the OP is asking is about how risky the connection is.
If the OP has no concern about being stranded for a day in AMS (single KL flight to CPT), or the stress of being rerouted via LHR (assuming KL propose it) and arrive over 12 hours late after spending some two days in planes and airport, then this is not risky indeed.
