Since the only way to win in sports betting, according to those who claim to be successful is to treat it like investing, I think that idea actually makes sense.
Taking sport betting as an investment does not warrant on winning anything, we are gambling to take the risk we have in it, when it comes we take it as it is, we can't predict on what may comes after playing a sport bet in gambling, not to even recall on how we often losses as we gamble then winning a bet, had it been that we all take it as an investment, then all of us would have been winning our bets taken.
