Everything depends on on several factors in gambling to put your ticket in that winning slot. From time, to your stake, to the odds and to how frequent other gamblers have won for the time, day/week.
I would like to add some reservations here that this describes casino games and not sports betting since the degree of wins obtainable from other gamblers has nothing to do with your sports booking, the outcome of every match is entirely dependent on the actions on the pitch.
Although there are some correct factors you mentioned that applies to sports betting too which is your stake, the odds present and also I'll add the good predictions you make out of your good understanding of the both parties involved in the match, but for the results, you rely on the outcomes after the conclusion of the matches.
