Not necessarily- I’m just a bog standard hobby gambler but have had a few ok random wins over the years which have put me ahead
The bookies probably class my bets as “mug bets” which is why they’ve never closed my accounts
Plenty of people I know run round at about evens, maybe a few quid down one year and maybe a few quid up the next
Not all gambling is problem gambling just as not all drinking makes you an alcoholic
The original thread was about matched betting and a few of the replies show it can be a profitable approach
