I believed that it is not really going to be easy to be hack, like if you click a link your not really gonna get hack that easily unless you just got trick into putting your information to a fake website something like that, its a different case if the telegram is the one getting hack, in this case its probably better to avoid strangers since you can already see that the intention of someone want to have a chat with you is to trick you.
Just be safe and don't click any link or install file sent to you by a stranger you met online. If you must, always scan to see if it's infected, because hacking has gone much more sophisticated than what you think. By mere clicking a phishing link, the attacker can remotely access your device and steal your sensitive information like social security number, credit cards details, password, seed phrase etc. If you're still sceptical, you may want to read this
