With the convenience provided by online gambling, we can play it anytime and anywhere. Online gambling can indeed make someone very addicted.
Where I live, gambling is an illegal activity and is often considered a negative activity, so it is very rare to do offline gambling, gathering in a certain place to play card gambling. I very rarely do they do that. But when it comes to online gambling, especially young people, many people are involved in this activity. And it is even impossible that today young people are not familiar with online gambling. Online gambling is like mushrooms spreading everywhere and many people are trapped in this activity. In fact, my country is one of the countries with the largest number of online gamblers in the world.
Gambling is highly addictive in countries where the practice is forbidden by local governments, as gamblers have no other alternative besides playing at virtual casino from the safety and secrecy of their homes or risk themselves are clandestine casinos where the police can come in at any moment. The accessibility such services provide lead gamblers into deep necessity for the activity, especially at the beginning of their gambling journey, where the losses from the long term haven't hit yet, and profitability is likely to be still going on for the gambler.
As consequence, gamblers get addicted to the profit they are making and don't want to stop anymore, until their luck finally changes to the other side and starts favouring the house. That is when the gambler should stop and break the cycle, and thankfully most do. However, there is always a minor portion of gamblers who won't give up, developing further addiction to the games, even though they aren't winning anymore.
Then we have a migration from the addiction to the profit, to the addiction to the gambling games, as profit isn't achievable anymore, but the gambler keeps insisting on it. This practice is pathological, because the individual gives up on his reasoning to continue playing without having conditions to afford to lose anymore.
