1. $100M TOCs include teams with salaries between 90,000,001 and 100,000,000. AAA players' real life salaries are factored into this total, which is why you see 80M teams in 100M TOCs (i.e., the real life AAA salaries push the team total to at least 90,000,001).
2. Every team in a TOC is a World Series finalist, so even the lowest seeded teams are good. Also, seeds don't mean much when you remember the teams all come from different leagues.
3. Upsets, especially in a short series, happen. What I've been doing (since about 2016 anyway) when a team of mine gets knocked off by a team I consider inferior is shout "FAKE NEWS!" at my computer screen. Try it! It actually makes you feel better!
