Will I be denied entry to Thailand due to my past visa history and stamps in my passport?

wow. You’re lucky. Certainly would have flagged that entry history as questionable. But it’s up to the immigration officer, so if they’re not having a bad hair day then whose to say what they’ll let pass.

that doesn't sound like Bangkok immigration, did you fly in at a different airport?

If questioned by immigration on arrival you need to provide 3 proofs for entry into Thailand.

1. 20,000 baht cash or equivalent in a major currency. It needs to be in cash. A bank statement, credit card or phone app showing you have funds won’t suffice.

2. Accommodation booked for at least the first few days. If you’re staying with family or friends then have them write an invitation letter for you to stay at their place.

3. A ticket out of Thailand booked within the number of days your entry allows, regardless that you can get an in country extension. 30 for Exempt, 60 for Tourist Visa (although the likelihood on being asked if you have a actual tourist visa is minimal). Bus train or plane. The two former must be an international ticket out, not just to a border town where you could walk across a border.

These proofs won’t guarantee you entry as that’s at the discretion of the immigration officer, but they’re the three things they’ll generally use as a reason to deny entry.
