high probabilities bets i.e. 98% winchance and such are terrible , they only work as a means to increase your wager
it is incredibly hard to make profit betting 1.01x since if you win you only get 1/100 of what you bet , but you lose every 50 bets on average
In the long term, there is no difference between betting on 1.01x and betting on 2000x.
As long as the house edge is 1%, you lose 1% of the total amount you wager. The odds doesn't matter in the long term.
