yeah I agree a lot with the article , in general profiting from gambling is getting harder and harder
as the writer said now most sports players are well trained and results are being hard to predict , also bettors now are doing more and more researches before betting
also in poker my friend told me that he was making way more money 10 years ago , and now he is still making money but his ROI dropped a lot
so the same thing also applies to poker , cause the average player nowdays is better than the shark 15 years ago thanks to the internet and other information resources
