Tag Manager: Bounce Rate to low

since the change to the tag manager the jump rate has gone down a lot. We’ve checked the numbers on the transitions, the bounce rate is really too low: 658 page views, 614 direct from Facebook and 598 exits - and Matomo shows a bounce rate of 19%…
I then analyzed the segmented visitor log: is it possible that Matomo evaluates visitor actions on the page (we measure an additional 3 scroll points) as another page visit?
Thank you in advance for your efforts!
Many greetings,
