Looking up "wagering requirements example" usually happens after a bonus has vanished, taking its winnings with it. The cause is almost always a condition in the terms: a deadline that passed, a withdrawal made too early, a cap on winnings or a clause about irregular play. Each of these can be seen in advance, and a short read of the terms shows which of them apply to any particular offer.
Many bonuses limit how much can be withdrawn from winnings made with them, often as a multiple of the bonus or a fixed amount. Winnings over that limit are taken back at conversion, even after the full requirement has been met. The cap is easy to miss because it appears in the general terms instead of the offer page. On a small bonus it can make a large win on a volatile game worth only a fraction of its size.
Every bonus has a deadline, and usually two: one for claiming it and one for completing its wagering requirement. When the second passes, the bonus and any winnings still tied to it are removed, however close the requirement was to completion. Deadlines range from a day for free spin winnings to several weeks for a large match. The clock often starts at the deposit, which means a slow first session already uses part of the time available.
Bonus terms include clauses on irregular play, and they are written broadly. Typical examples are betting on both sides of an even money bet, switching to low risk play to clear wagering, raising stakes sharply after a bonus is converted, or opening more than one account per person or household. A casino that finds such a pattern can void the bonus and its winnings. Reading the clause shows which patterns a casino names, and which ones it leaves to its own judgement.
A saved copy of anything support agreed settles disputes far better than memory, especially if the promise is later questioned.

Often yes. Asking to withdraw while a bonus is active can remove the bonus and its winnings, and some casinos apply this to the deposited cash too.
