stalemate

Giving checks multiple times to the opposing king without them having any available pieces to block the check

Giving checks over and over is not stalemate but repitition

It ends up as a stalemate.

No, a stalemate is when the king can not move into a clear (unchecked) position. Draw is when both sides do the same move 3 times and a draw is also when time runs out and there is insufficient material (which has happened to me and I think its bs lmao because in my view I was winning) .

Well idk then. This guy who ran a chess tournament told us that 3-fold repetition ends up as a stalement. Also, he said that stalement and draws are technically the same thing.

Stalemate is "its turn of one side that has no legal moves but isn't in check". A draw is a draw, result between win and lose. Stalemate is, in chess specifically, one of events that result in a draw. So you could say stalemate is a subtype of draw. Not exactly "same thing" tho.

Serious advice: you should look up what stalemate is. You obviously don't know, and it's very difficult to play chess without it.

Another serious advice: please don't give advice about things you don't know.

Stalemate usually never happens but it’s safe for who isn’t ahead in material

I got the 'advice' from someone who is a qualified coach and arbiter. So I believed him, and many people also told me the same thing.

No qualified coach and arbiter would confuse stalemate and 3-fold repetition. that's just not possible. You probably misunderstood what the guy said.

'5.2.1 The game is drawn when the player to move has no legal move and his/her king is not in check. The game is said to end in ‘stalemate’. This immediately ends the game, provided that the move producing the stalemate position was in accordance with Article 3 and Articles 4.2 – 4.7.'
