No. Sports betting is not legal in Vermont, but a bill is in the works and could be approved by 2021. The state has to vote on another bill in May 2020 that would approve for a committee to study how to tax and regulate sports betting, which will conclude December 2020. If all goes well, sports betting could go into effect July 2021, though the official launch will likely be after that date.
Of note, this is a mobile-only sports betting bill, which comes after neighboring New Hampshire launched mobile sports betting in 2019. Given that there are no casinos or federally-recognized Indian tribes in Vermont, this isn't a major issue. In-person betting may be legalized in the future, but launching online sports betting first is a good start.
Vermont passed legislation for the legalization of Daily Fantasy Sports in 2017 with a standard set of regulations including a minimum age of 18 to participate. Horse racing betting is also legal and can only be done online.
