You are not far from the truth, though I have never used the land base casino I have an uncle then who will leave home and spend almost the entire day at the casino hall, the online is just for stake, play and take profit, you can't socialise, maybe when the metaverse is in full operation we can start enjoying the online casinos.
Even though you can't socialize, anyone can enjoy online casinos because now there are many choices of platforms that provide this and everyone just needs to make a choice for them to try. And I think that with the existence of more services from various platforms for casinos, it won't be a problem if someone doesn't try land-based casinos manually like your uncle did. Because now almost everything can be accessed via a smartphone that has an internet network.
