The point is to find out whether success in gambling depends on how often we gamble.
No, it does not depend on that. If you mean in the short term, like getting a big win in the slots, that's totally random, and it doesn't depend on whether you play more or less. In the long term it doesn't depend on it either, as you lose money on the house edge.
What can happen is that because of what you say is that when you play more often you may play more tired or stressed and make worse decisions, like for example when you win and the session leaves you with a net profit, instead of stopping you continue, and you end up losing.
