Weird ad times on youtube?

Okay so I'm just here watching YouTube on my TV and I don't have premium (like a normal person,) So obv there's ads. But the thing is that there's like 60 second un skippable ads but they claim it's so you have less ad breaks (btw I like watching longer hour long videos,) I haven't timed it but I can't help but realize that it feels like it's the same amount of ads? Whenever I watch a 20 min video compared to a 2 hour video fsr it's like on the 20 min video I get ads that are usually like 15 secs every like 10 mins, but on a 2 hour video I also get ads every like 10 15 mins but it's fucking 60 seconds and unskippable wtf. Like am I just tripping or is anyone else noticing this. Ps this only happends on my TV not any other device??
