Again, I am speaking from my own experience

I don't feel worried about it. I watched a few babies who were into tub sucking, and all of them had almost unnoticed switch to no thumb sucking, when they got to the age they were more interested in others things. Now I am not saying it is always the case. But I figured out, my baby will be so busy discovering other things that he will not be that interested in his thumb

from one day to the next when she was about 8 months old. Just some thoughts...
Also usually the sucking need diminishes by around 9 months and the great majority of children stop thumb-sucking spontaneously as they get caught up in learning new skills like crawling and walking, and no longer need to be stimulated or comforted by sucking...
