If I understand your question properly are you asking if you can publish a press release that has been put out to the online gambling industry on your website?
If it is a true press release I don’t think you should have any copyright issues as it was a “press release” and the company doing the press release should expect that it will be reprinted on several news sites.
Now if it is just an article on that individual companies website about the online gambling market, you better ask first. Hopefully that helps.
