The game's RTP isn't 1%. That's the house edge. The house edge is 1%, the RTP is 99%. That means that if you bet $100, you will get $99 back on average and in the long run taking into consideration millions of rounds of play. It also means that the casino (the house) profits $1 from the previously mentioned stake. This is just statistics and it's impossible for one single player to experience this on his own. It is more realistic that you will win much more or loss much more.

Just because you saw one number appear more often in X rounds, doesn't mean the game isn't fair. If you thro a coin in the air 10 times, you can't expect it to fall 5 times on heads and 5 times on tails just because the chances of heads or tails are 50/50. It might fall on heads 8 times.
