Having seen or have had first hand accounts of things going wrong on DSDs or try dives I would advise starting on a proper course such as PADI scuba diver where you will learn basic skills and understand the risks before going to much depth. Things that have gone wrong on try dives among people I know or have first hand experience are, ran out of air at 13m followed by panicked ascent (never dived again), Mask filled with water, reg spat out and panic ascent from about 7m. Reg out of mouth, panic, water inhaled at about 10m followed by night in hospital. 2 cases of failing to equalise causing severe ear pain/problems and trips to doctor or hospital - rest of holiday spoiled.
