My advise would be:
- you have to assure yourself, not by others, otherwise there always be a shadow of doubt which is not good by any means.
- if something is stated wrong here, “seniors” would most probably react, especially if wrongs are stated by “juniors” (like I am). I’m finding the proof in that @adw reacted on your wrong comprehension of his words, and on nothing else in this topic.
Conclusion: dare and believe in yourself. I hope you’ll find only positives in my post.
