You need to know what works for each game type. For casino and slot games, luck factor is needed and strategy may not be as effective. But for sports betting, analysis can increase your chances of winning.
If you can analyze games for sports betting but choose to rely solely on luck without a strategy, that's like being lazy. In sports betting you can put in effort to analyze and make better decisions.
For slot games, I'll say be wise with the about you bet with. Don't spend anyhow, or use a strategy that'll make you go keep doubling your bet amount without seeing tangible wins. Manage your money wisely when playing slot games.
You just said my mind cause from what I know about gambling, that's just it, success is mostly by luck and good strategy, well I'm more of a sports bettor than slot games cause winning from slot games is mostly by luck it's not like sports where you need analyse the strength and weakness of different teams playing against eachother to know the most likely outcome of the match, you'll need to research on the team with the best form, better players and so on cause it would help you pick the odds that matches your analysis and produce potential good results. Anyways regardless of whether a gambler goes for either slot games or sports betting the person would need to manage their funds and avoid overspending.
