There are two main types of gambling: Chance-based Games such as Lottery, Bingo, Keno, Slots, and Andar Bahar, where randomness defines the results and winning or losing depends entirely on luck are all conducive to chance-based gambling. Skill-based Activities such as cricket betting and horse race betting, or games such as Poker, Blackjack and Teen Patti, where your playing skills define whether you would lose or win (even if the house always has the edge), contribute to skill-based gambling.
