Gambling is a high risk way of making money, this is not for everyone, only few people are successful with investing in gambling, investing in the sense that they are gambling for a living.
Not making money, the right word for it is that you have a chance to win money. You are making it sounds it is some kind like a job. Not entirely true though, just correcting this statement
Gambling is not a job or a business or an investment, but many people have this sense in their mind which is totally wrong. Also i think Casino are locked down for a long period of time and even if lockdown is lifted across the countries, the crowded places or places where public gathering is expected, they will remain closed for a long time period. So only option for everyone is to play online gambling.
It has been applied at this time where any crowd should not be done including offline gambling and therefore people will move to online gambling because it is one of their ways for gambling lovers but is it possible they will be happy by continuing to play online gambling? only partially.
Nowadays there have been many online gambling introductions through paid advertisements, so there is a lot of interest in this pandemic and many people do online gambling, including many casinos.
A professional will certainly know when to play gambling to win.
