Casino is a place where you where everything is for you, just make stakes. You can eat, drink, smoke a cigar or whatever you like.
But it's only in normal casino, not internet.
Casino gives you an ability to get money, but with 40-48% chance.
That's why poker is better.
Casino is for fun.
I knew a few casino pro, who knows how to play blackhack or russian poker with better % of win, but they are usually banned in
casinos )
Have fun and good luck.
