Is a crypto exchange wallet a hot wallet?

Could you elaborate on whether a crypto exchange wallet falls into the category of a hot wallet? In the realm of cryptocurrency, wallets are often categorized as either hot or cold, depending on their level of accessibility and potential exposure to risk. Hot wallets, as the name suggests, are typically connected to the internet and may be more vulnerable to security breaches. Given the nature of crypto exchanges, which often require online access for trading and other functions, I'm curious if their associated wallets are considered hot wallets and thus, potentially more susceptible to hacking or other security threats.
