I highly doubt you can remove them - best case disavow them.
At this point, if you are willing to roll the dice, see what kind of effect the links will have on your rankings. Understand that those links are textbook spammy and should be treated negatively (they are irrelevant to your website, have lots of spammy outgoing links) but Google makes mistakes.
It is probably a matter of time before those links will be considered negative/poor and likely to hurt you down the line. However, it could be months/years before that happens.
If you are already ranking well some some terms and are scared of losing rankings, i'd disavow them now.
