Starting from my own end, here is my definition and understanding between the two.
Casino Gambling involves Playing games that are base on luck factor and sometimes our skills also work out in this, it does not involve live event.
Sport Betting simply means, playing on live matches which involves you and a particular player or team against each other.
And as according to research, you can also see the various opinions given on what the two stands for and their respective examples in which constitute each category.
I always prefer casino gambling to sports betting. Casino gambling is rational, sports betting is emotional. In Casio gambling, besides the luck factor, knowledge and caution are extremely important. In sports betting, however, these may not be enough. There is a lot of interest in sports betting nowadays, which is why there is a lot of match-fixing and shady situations in this type of betting. In casino gambling we always think that the table will win, but if you know enough combinations you know where to stop after winning in the casino. This way you can make a regular profit in the casino, even if it is not constant. In my opinion, casino gambling is much easier to win than sports betting.
