Gambling games are really designed that way which is their player normally losses on the long run. Agree, thsoe techniques or ways you used are just holding and making your bank roll last while you play in a matter of time but still it would not change the result in the end unless if luck saves you for sure you would gain profits same as you said.
That's why avoid those pure luck gambling games like dice and slots as it will only lead to the one result, being a loser for a long run.
Strategy based games are more worth to try as profit here is more possible.
think some like small invest..1.5 payout 1.8 payout...something like that
