You can always win money, that's how gambling works. But odds are you won't, especially in the long run. Many gamblers are gambling every week searching for that high of a win. One day they'll get a big win, say £500. But they've already spent £2,000 in the past weeks, months, years, maybe even that day.
Just play them for fun. No reason to bet money on it, arguably unless it's something like poker and you're a pro at it.
