No, most people will expect that they won't win and also won't lose their capital. 100% RTP means that the casino gives away 100% of what it receives but you shouldn't really expect that you'll start playing and in 5 minutes, you'll sit with the same capital. 100% RTP is the best for those who participate in a wagering contest because if they place millions of bets, they'll get 100% of their money back. This process is like, you might lose 100% of your capital in 5 minutes, then deposit the same amount of money, then you win 200% in 15 minutes, then you lose, then you win again but after hours of placing millions of bets, if you check the statistics, you'll be left with what you deposited.
