Why its a draw?

Because your opponent ran out of time but

you did not have enough material left to force mate.

You were black. Your opponent ran out of time.

You cannot win because you cannot mate your opponent.

That's a rule.

You cannot mate meanwhile your opponent ran out of time, so it's ended as draw.

No, it was stalemate, the clock just showed up as that.

It's obviously not stalemate. Look at the position again.

It's not stalemate, mb

(one legal move)

I still don't understand if he ran out of time I should win right? and even it's not and it's my turn I still have a move to mate him that is a weird rule still don't get it happened to me many times

First of all, as far as I can see, none of the 2 account are yours. But never mind that, here is a detailed explanation.

In your example, black had a king and queen, and white had only a king.

Black (who had sufficient material to checkmate) ran out of time.

He was a move away from checkmate, but his time has run out. That is why he couldn't checkmate.

White doesn't win because white has only his king left, AKA he doesn't have sufficient material to win this.

If white had a single pawn on the board, he would've won this game.

If both people have sufficient mating material, whoever runs out of time loses.

If one person has sufficient mating material and the other does not, and the person who does not have sufficient mating material runs out of time, he loses.

Various places have different wording and perhaps what is considered not sufficient mating material, as far as I am aware they all agree on this. If it is impossible according to their rules to mate, then that person cannot win. SO when a person with enough material runs out of time they get a 1/2 win, because it was impossible for the other to win. Vise versa, because the person who had enough mating material ran out of time then the side for which it is considered impossible to win (by checkmate), is awarded the other half of the win.

First game go-ve (white with lone king) vs JackMaVietnam (black with KQ)

JackMaVietnam (black) ran out of time in this game so each was awarded a 1/2 win. If white had run out of time then black would have won it all.

Second game - RidaS96 (white with many pieces) vs Vanzkaler(black with lone king)

RidaS96 (white) ran out of time so each was awarded a 1/2 win. Had Vanzkaler (black with lone king) run out of time them white would have won it all.

It’s a draw because neither side gained the upper hand. Whether it’s skill, luck, or circumstances, both sides matched evenly. Sometimes, it’s just how the game unfolds—nobody lost, but nobody won either. That’s competition for you; not every battle has a clear victor, and that’s okay.

Timeout vs insufficient material happens when a player is out of time, but the other player does not have sufficient material to checkmate

In this case, black flagged and was down to 0 seconds, had Mate in 1, but lost time, and white only had a sole king. Only a king cannot checkmate another king, but White had time with no sufficient material. That's why, draw. This is actually very fair, as sometimes I lose my own time, but my opponents do not have material to checkmate, so it's a draw. Lichess does not follow this rule. I am not disrespectful, but just saying that Chess.com follows the rule of USCF (which has this rule) and Lichess follows FIDE, in which it states that even when you are out of time you lose, no matter if the opponent has sufficient material or not.

I get that, but how is it obvious? I looked for 1 minute to find the only legal move.

Be nice

At your rating that's a bit weird. You are not a beginner. Maybe you had an off day.
