Can someone steal your info if you use PayPal?

Good day, I've been wondering about the security of using PayPal for my online transactions. Could you please clarify for me: is there a risk that someone could potentially steal my personal information or financial details if I use PayPal to make payments or receive funds? How does PayPal protect its users' data, and what measures should I take to ensure my own security while using the platform? Thank you for your time and attention to this matter.
