Google Sheets: How to have conditional formatting based on each individual cell?

I have a Google Sheet where it's a table full of people's Euro Cup soccer picks. I want to have a column at the end where I type the winning team into a cell. If that value matches then I want the cell to turn green, or else turn red, else if empty stay white.

I can do conditional formatting for every single cell but this would take forever since there's hundreds. If I select the range, can I do a formula where I specify that cell? Like how if I type row() it gives me that row, can I do something like -

if cell() === row() column 50then greenelse if cell() === ""whiteelse red

I need some help with the syntax too if this is possible

*Edit - Here is an example of my sheet https://docs.google.com/spreadsheets/d/1KcUnRg2UuqfnjX7TehAAluNEcDDbs2utErh1eLPczNM/edit?usp=sharing

I want conditional formatting so that the cells in A to E change color depending on the text in Cell F
