Gambling is based on luck for real but that doesn't mean you should be dividing your attention into poker, soccer, horse racing, or roulette all at once, you need to choose a side and learn everything you can about the game. This is the mistake that many gamblers are making, they believe since it's all about luck they should expand the possibility to get lucky and it always end up badly for them.
It's no doubt that Poker for example is all about been cunning, logical and deception to gain power over your opponent, it's called upper advantage, this is way different from games like Blackjack, roulette or Slots.
So imagine doing all these together, most gambling games needs your understanding of the odds and taking them into account, especially when wagering, so how can a gambler get involved in all games at once just to increase their chances of getting lucky? Stop this as it's not a strategy to win, it's a strategy to lose.
If a gambler has enough free time and money, then why shouldn’t he play everything? It seems to me that the mathematical chances will be the same even if he plays dice for 10 hours or different gambling games every hour (it is clear that the casino advantage is slightly different everywhere, but the general meaning does not change) for 10 hours.
The most important thing is to have fun, there is no winning strategy (even in poker).
