Dear teacher,
Am I right that the verb "thumble" is the eqivalent of "hitch-hike". Thank you in advance.

Good morning Olga, that is exactly what it means. She hitch-hiked.

Hello Olga,
As far as I know, "thumble" is not a word at all.
To "thumb a ride" means to hitch-hike and it's used as a verb in this case.
I'm assuming thumble is a typo.
