Nope, there is no guarantee that you will get greater chance to make profit if you play longer.
The result in any game of chance is pure about luck, it may come as soon as you start or it may not come even if you play longer.
If you think that you will get greater chance, it will just make you being trapped as you will push yourself to keep playing as long as possible till you have no more funds.
If you play longer it simply means you are getting closer to the probabilities, which means that you will end up losing money as that's how every single game is designed.
So, if you happen to win big, you should stop immediately to maximize winnings.
If you never play you are actually maximizing your expected winnings, neutral, or zero, whereas if you play your expected return is negative in the long term.
The theoretical RTP is based on hundreds of million/billion of bets, so one player who plays longer won't be getting near "the probabilities."
But, there are comeback mechanics that vary based on the game's volatility, so you'll get something back if you play longer or have sufficient balance.
If you win big, the next spin still has the same probability, maybe you will still be lucky in your next spin, or not.. who knows?
The mistake for most players is to catch the falling knife and deposit more to return their losses, while immediately quitting when they are in green.
