Student's at uni shouldn't gamble because they're at university to study & learn. If their focus gets distracted to gambling they shouldn't have taken financial help from their family to pay their uni fees. They should get good grades & find jobs to begin earning.
If students are addicted to gambling at a time when they need to study deeply, then they will not be able to acquire the knowledge they need, which will cause great harm at some point. There are many gamblers who fail to achieve their goals after studying for a long time. Gambling can be done at any time in life, but if you cannot study at the right time, then it is no longer possible to study. Everyone should definitely do their work on time.
