O365 anti-spam EOP vs ATP

Question

Hello,

I can see that Business plans https://www.microsoft.com/en-ww/microsoft-365/business/compare-all-microsoft-365-business-products?m...
include EOP "Protect your email against spam, malware, and known threats with Exchange Online Protection(EOP) And enterprise plans https://www.microsoft.com/en-us/microsoft-365/compare-microsoft-365-enterprise-plans?rtc=1#coreui-co... include ATP.

What is the difference between EOP and ATP? I have only 50 users and Microsoft 365 Business Standard plan . EOP is includeded in business standard plan and it is enough for anti-spam? I don’t need anything fancy,just basic anti-spam.
Thank you
