Energy is always required to break bonds and always is released when bonds are formed, even with ATP, but the part that is omitted is that more molecules of water are bound and ordered after the ATP hydrolysis than before and so more ordering plus many more highly energetic hydrogen bonds formed than broken equals a large overall release of energy for the overall process.
ATP is at a high level of chemical potential but the type of energy released from its hydrolysis depends on the application. The short answer is that the hydrolysis of ATP to ADP always releases heat, and if coupled with a cellular process it additionally produces either chemical potential (in another species) or work. Let me back up a bit, and note that ATP is a species that has a high degree of potential energy.
