No. The winning chances will remain the same. By studying and researching you will only be able to manage your bankroll more efficiently, what means it's likely to last longer, as you avoid wasting it on worthless or desperate bets. However, on long term the most likely scenario is that you will still lose money the more you play.
Of course to be lazy isn't a good thing, so make sure to spend time and energy on something which will bring you positive results along the time the more you dedicate yourself to this. And gambling isn't one feasible choice, as your effort won't mean much, considering outcomes are random and unpredictable, doesn't matter how hard you try.
Hard work will matter in other things where practice matters a lot, like in sports, music or other similar things. And in betting, you can spend hours studying a match, and then some force majeure will happen that will affect the outcome of the match and it will be an accident that could not be taken into account before the match and it does not matter how much time you spent on its analysis 15 minutes or 3 hours. And if we talk about other games, then only luck will matter there...
