Your post doesn't specify a question...kind of hard to help.
www.pokerstove.com will give you the equity of a hand against truly random hands. Does this mean you should be playing every hand with positive equity against random hands to the river, regardless of the betting? No. People fold. The example that was given in the article was purely an exercise in mathematics and really not applicable to a real world scenario unless you were playing against people that literally never folded. You'll notice the equity shifts as the number of players involved in a hand increases/decreases...so if 10 people are dealt in, and 8 fold, your equity is dramatically decreased percentage wise.
