Does changing the bet size change how often a slot pays?

How to use this answer

A definitive win, loss, void or refund cannot be established from the question alone. Identify the operator, the exact market, the date and the relevant official result, then check the rules that applied to the bet.

Return-to-player and volatility are statistical properties, not promises for an individual session. A streak or a near miss does not establish that a particular spin is more likely to pay.
