RTP describes a theoretical average across a very large number of plays. A value of 96% does not promise that your next 100 units will return 96. A short session can lose the entire amount played.
Read the exact game version’s help screen: stake, paylines, winning combinations and bonus features. Different configurations can have different rules. Volatility describes how uneven results can be; it is not a method for predicting the next spin.
On independent random spins, a run of losses does not make the next win due. Increasing stakes to recover losses changes the amount at risk, not the underlying odds.
