The Ospreys rookie was one of the stars of the tournament as Wales reached the final in France.
But they crashed to defeat against England at the final hurdle and Evans admits it was hard to take.
“It was my first World Championships and I didn’t expect it to be that good at all. It was a crazy experience,” said Evans.
“It was a bit surreal, and thinking back now it still hasn’t sunk in fully.
“It was disappointing not to win that final match, but we must realise that we were the first Wales Under-20s team to reach a final.”
Evans crossed for two tries in the final as Wales led at half-time before eventually succumbing.
“For me personally, that first half was incredibly special — then it was such an anti-climax to lose the game,” said Evans.
“We had played England in the Six Nations so we knew they were a beatable team, and we’d just beaten South Africa in the semi-finals, who had beaten England in the group stages.
“After the first half we proved they were beatable. But in the second half they just came out a lot stronger than us. To be fair they were the better team.
“The previous under-20s side had reached the semi-finals in South Africa so our targets were to match that.
“When we got to the semi-finals we knew it was an opportunity to make history by reaching the final.”
Having starred on the world stage, Evans is now aiming to make the step into senior regional rugby.
And he reckons he is well placed to reach his potential at the Liberty Stadium.
“First I need to develop within the Ospreys region,” added Evans.
“I’m currently with Bridgend so hopefully I can make a mark with them and hopefully push on to get some game time with the Ospreys this season.
“It’s such a good stepping stone. You see the likes of Dan Biggar — now they’re in the Welsh set-up.
“This is a really good pathway for development.”
