The some is actually small compared to the opposite( atleast from the onow datas ) but every gambler is likely competing and hoping to be among the small percentage yet gambling is not a source of income and shouldn't be treated as one IMHO
His post said 50% of the population are gambling, but it’s not about who actually makes money from it. It’s easy to find numbers on how many people gamble, but when it comes to how many really earn or make it a source of income, there’s no solid data available for that.
Even the total number gamblers can't be accurate... there will be more but yeah, it can be fairly judged from the available data.
