You got a point.
But I think what he's trying to say was since we've got no choice but online gambling sites, people started to adapt it. Government even allowed it because it could lessen the people that could go outside just to play in the land based casino because way back 2020, COVID-19 was too wild compare to now that it somehow lessens because the vaccine was already released in public.
At some countries, land based casinos already started to operate but there are more countries where they still prohibit land based casinos to operate, therefore people still appreciate online gambling sites.
And now with another covid variant (delta) the chance that the spread is much quicker,
We would expect more gamblers who learned how to use online platforms to continue using it, they might concern about this new virus to spread with their love ones,.
from where am I, offshore casinos are still not allowed to run forcing those owners to open up their business online since they already have patrons who keep asking, they are now adopting and moving forward to continue.
