✅ How does CultureInfo works in C#?

Hello guys, it's been quite a few instances now that I came across CultureInfo. I encounted it when comparing strings and when comparing dates. What I understood about it is that, if we don't specify anything, it uses the locale system of our machine. So if our machine is set to en-us and we try to compare something with de-DE, their might be issues here? I know the "ß (Eszett)" stands for "ss" I think... so, what kind of issues might arise?

If we write something like this for eg:

C#
var str1 = "Grasse";
var str2 = "Graße"
if (str1 == str2) ...

str1 == str2 will return false in this case (If we don't change the CultureInfo thing)?

Now there is also the CultureInfo when we use dates. This is where I'm the most confused. When we use methods like TryParse with DateOnly, it may happen that the overload contains the IFormatProvider interface, so basically these are "settings" to change the culture specific.

For string I did understand what it does (but please someone confirm if the above statements are correct please.), for date, it's a bit ambiguous though. So say my locale system has culture en-us, basically, this mean that my date format is specific to the us culture. How will that affect my TryParse or TryParseExact?
