About to close on my first deal. Just had a sewer scope done. Is this a concern ?

[Gurjot Grewal]

77 feet, cast iron and clay pipe. Home is built in 1952 on a slab. Findings are "Typical Root Intrusion", "Openings or inconsistencies noted in sewer line, signs of settling" recommendations are regular inspection and maintenance. 

I'm not well versed on plumbing. How does this sound? I'm assuming the cast and clay pipes will eventually need to be replaced. In the video there were no large obstructions that I noticed. In the residential disclosure the sellers wrote that the main sewer was serviced in march 2020 and cleaned in march 2023. The inspector was told by the tenants that they got it cleaned a couple times. The video still shows some tree roots even after cleaning. But the water seems to be flowing well, no breaking was found and I'm told that no immediate action is needed.
