You really cannot gambler they always find a way even in the worst-case situation like the pandemic, how about in your country do you have some people who cannot stopped to gamble even when your country is in lockdown
A pandemic is not the worst situation.
The Internet continues its work, people are safe at home, sweepstakes of events continue to work, which allows you to bet on anything other than sports.
In other words, the gamblers were cut functionality did not cut off the ability to bet.
If war broke out, interruptions in the Internet, mass extinction, then believe me, a very small number of people would continue to go about their gambling addiction in a prejudice to preserve themselves.
Nothing can stop, life simply goes on.
Internet had changed the way we live and this pandemic will change it more. Those who were gambling at physical casinos might have faced a little problem in the early days of lockdown. At present I guess most of them are busy gambling on online casinos.
I am sure untill the world exists gamblers will find a way to gamble.
