Does Polish keyboard layout exist?

In Croatia, we have a special QWERTZ keyboard layout that has diacritic symbols on the right of L and P keys, but also markings for ł and Ł, which are exclusive to Polish (to my knowledge). We type @ with altgtlr+v combo.

People I know from Poland have a QWERTY keyboard and the shift+2 combo for @ and no markings under K and L for ł and Ł. This confused me greatly, for how does the Croatian keyboard have those two polish symbols and the Polish one doesn't.

So I assume that it isn't the Polish layout, but the US one. Inspired by the recent map I saw of Europe with countries marked by whether they use QWERTZ, QWERTY or AZERTY, on which Poland is mixed between QWERTZ and QWERTY, can you tell me if there is a Polish keyboard layout and whether it's used on keyboards at home and schools and public places?

The photos are of the Croatian layout and something I can only assume to be the Polish layout, but does it actually exist and is it used?

Thank you!
