There are ads in the old version too. They show up as sponsored posts though I don't know if they are as egregious because I also use old.

The only thing that I feel I miss out on in using old.reddit.com is the predictions. The /r/muaythai has a predictions tournament that's pretty fun but there's no way to get notifications that there are new predictions to be made with the old interface (as far as I know).

Use an ad blocker. I use ublock origin and don't see any ads on old.reddit.

I also use ublock origin, but it doesn't imply that there are not ads.
