For daily prayers, yes that is a daily occurance. We pray 5 times a day but only the afternoon prayers are something we'd need to take a break for.
But you can work around it and you might only need to take a 5 minute break once a day. So like the post and you have mentioned it's not that much of an interruption.
However, Fridays are a different story. We have to go our sermon which might be an hour so. In the US Saturday+Sundays are off so that's not something that would interfere with a work/school schedule. Personally, in our high school we held our own prayers after school on Fridays. But I know for a fact that didn't work for all my Muslim peers.
Holidays are another issue, we'd need to take 2 days off a year to observe our holidays. I wouldn't go as far as so say this is systemic oppression. You just get an excused absence or use pto lol.
Where it would become a problem is if your requests to take off work/school were to be denied. But thankfully that isn't usually an issue in the US.
Besides, in some school districts non-Christian holidays are starting to become recognized and may already be off.
Overall there is a consistent minor friction causes by daily schedule differences. And especially in school a student may never even ask for accommodations for fear of being "different". Even though when you ask generally when you ask you will be accommodated.
