Richarlison only appeared for the final 20 minutes as Spurs exited the UEFA Champions League at the round of 16 stage following a 0-0 draw with AC Milan in North London on Wednesday.
Conte's side lost the first leg 1-0 in Italy.
Richarlison has started sporadically for Spurs since completing a £60m move from Everton last summer.
The 25-year-old has failed to score in 17 Premier League appearances so far, with his only goals coming via a brace against Olympique Marseille in the Champions League group stages.
Richarlison is up against Dejan Kulusevski and Son Heung-Min for a starting berth in the Spurs attack but he feels he should have had a better involvement in games thus far.
Speaking to Brazilian TV station TNT Sports after Wednesday's match, he said: "I should have played.
"I was playing well, we won against Chelsea and West Ham and suddenly I was on the bench.
"I played five minutes against Wolves, asked the reason and no-one told me why. Yesterday, they asked me to take a fitness test in the gym and told me I was going to start today if I passed it.
"And today I was on the bench. There are things I can't understand. There was no explanation again, let's see what he [Conte] will tell us tomorrow - but I'm not silly, I'm a professional who works hard every day and I want to play."
"There hasn't been enough minutes given to me. I don't have enough minutes, was injured for a bit, but when I'm on the pitch I give my life," he said.
"I played well in two games, especially against Chelsea, so I think I should have played tonight, but I can't go on crying about it now."
"We have 12 games to play now and the focus is that," Richarlison said.
"I'll try to score as many goals as I can because the club has paid a lot of money for me and I haven't given enough back on the pitch yet.
"Fair to say my injuries didn't help and I haven't had enough minutes. But now I'll go home, rest, train tomorrow and see if he'll put me in the first XI next game."
