IMO, he only refers to (a way of making money) and according to him gambling is one way of making money, without realizing that gambling is just a place for someone who wants to find entertainment with a little money and if they are lucky, it is a little bonus from the fun we have pay.
But I like the quote, because it make some gamblers aware that they may be addicted because they are triggered by the desire to earn large amounts of money from gambling and this quote from Erigga can give a slap to gambling addicts who only think about earning money from gambling.

And back again to each individual's thoughts because betting shops and investment banks actually have different meanings but sometimes someone interprets both as the same as making money, but not for me.
