Depending on the casino you are using, but generally speaking, the answer is no. Why? Because they are not charity, casinos never give away bonus money for free. They created a set of guidelines, referred to as bonus terms and conditions, that you must go by if you don't want your wins to be cancelled. Bonus requirements are a tactic used to make it more difficult for you to meet the wagering requirements.

Most casinos need you to place a wager in order to use an active bonus. Typically, the wagering requirement is a multiple of your deposit plus the bonus you received.
What you should also be aware of is that, in order to comply with the bonus T&Cs of the casino, you typically have a few requirements to meet while trying to fulfil your wager. Your maximum permitted stake per spin or play round is the most crucial requirement. When playing with an active bonus at other casinos, you occasionally have restricted access to certain slot machines. Before you begin playing, always read the bonus terms and conditions page of the casino. Your session will terminate without any unpleasant surprises if you comprehend and abide by these terms.

Although they are less common, no deposit bonuses are very popular with players who want to test out a casino before making a deposit. Free spins and bonus money are the two subcategories of no deposit bonuses.
The casino may offer you extra cash or free spins when you register. Free spins are often meant to be used on slot machines that the casino has selected. If you play at a casino that offers bonuses, be aware that there is a maximum withdrawal amount for the bonus wins.
