I've seen both but sports seem a lot easier to me and casinos are hard for me.
- What do I need to know to play casino?
- Which is a more profitable casino or sports game?
- And Which Platform should take as a newbie gambler, casino or sports?
This is my take:
You don't really need to think that knowing how to pay casino is complex and have more to it, you can just try watching youtube videos on how you could play casino games (as the word 'casino' is a general term for a place of gambling -- which can offer tons of games from blackjack to slots) and have fun with one. If you are pertaining to poker or blackjack in casino, then watch videos or introductions online on how to start with it.
In terms of profits, really depends on how you are good on both. If you are good enough in casino games such as you have enough knowledge in reading and counting cards for blackjack or is good at game sense in poker, then casinos can be more profitable. But if you are onto sports and knowing each and every detail that could affect the factors of winning of a team in a game, then sports betting is your money maker.
Lastly, with the platform to use for a newbie to be a gambler, I think casino is the way to introduce them to gambling. Why? They control their money with their skills or luck while in sports betting they risks their money for chances of winning of the team/others. Hence the way to learn how to control your gambling activities is to know how you behave with your own games.
There's a study[1] that compared between casino gambling and sports gambling had more problem-related-gambling exclusion and Sports betting has a higher rate, therefore making the casino gambling way less problematic in the long run.
