Experts treat gambling as a source of income, so they bet on themselves because they’re confident in what they’re doing and believe they can be profitable. These are the ones who raise a realistic bankroll and set realistic targets. let's say on average, if their funds grow by 10% in a month, they’re already happy because over time, it compounds.
Meaning, they don’t cash out their profits right away, they reinvest it as additional bankroll.
Now I’d like to ask you.. as a gambler, would you already be happy earning just 10% profit from your total bankroll?
You need to be a whale gambler to be conformable with 10% of your bankroll every month, this is if they choose gambler as s a source of making income which I strongly will advice against the idea, in every way possible don't ever turn gambling into any form of making money monthly or weekly.
Things won't always work out even if you are an expert, I would rather invest the money into something more reliable, 10% sound achievable in many other things out there, even staking have proven to be this great depending on the asset.
Sorry my answer will be a big no in capital letter, and if you believe that anyone is making this idea work then speak on behalf of the person, it's either they are lying or they have a motive to lure people into gambling.
